Introduction
Mobile applications have become one of the most important advertising environments in Turkey. Consumers use mobile apps for shopping, food delivery, gaming, banking, travel, fitness, education, entertainment, social media, messaging, health services, subscription services and financial transactions. As a result, advertising is no longer limited to banners, television commercials or websites. It now appears inside mobile applications through in-app banners, pop-ups, push notifications, rewarded ads, personalized recommendations, sponsored listings, app store previews, referral campaigns, influencer links, discount codes, subscription offers and location-based promotions.
The subject of advertising law for mobile applications in Turkey is therefore highly important for app developers, e-commerce platforms, marketplaces, game publishers, fintech companies, health and fitness apps, education platforms, food delivery apps, travel apps, social media platforms, advertisers, agencies and foreign companies targeting Turkish users.
A mobile app advertisement may appear in many forms. It may be a banner shown inside the app, a pop-up during checkout, a personalized product recommendation, an in-app purchase offer, a push notification, a subscription renewal message, a sponsored search result inside the app, a discount campaign, an influencer-linked landing page or an AI-generated promotional character. Regardless of format, if the message promotes goods, services, brands, sellers or commercial activity, it may be subject to Turkish advertising law.
The main legal framework includes Law No. 6502 on the Protection of Consumers, the Regulation on Commercial Advertising and Unfair Commercial Practices, electronic commerce rules, distance sales rules, commercial electronic message rules and Personal Data Protection Law No. 6698, known as the KVKK. The Advertising Board, known in Turkish as the Reklam Kurulu, supervises commercial advertisements and unfair commercial practices directed at consumers.
Mobile app advertising became even more important in 2026. The Ministry of Trade announced that amendments to the Regulation on Commercial Advertising and Unfair Commercial Practices were published in the Official Gazette on 1 July 2026 to strengthen consumer protection in digitalized markets. These amendments introduce rules on targeted advertising, AI-generated advertisements, influencer promotions, discount advertising, consumer reviews, environmental claims and children’s profiling. The new rules are scheduled to enter into force on 1 August 2026.
This article explains the key legal issues in mobile application advertising in Turkey, including in-app ads, targeted advertising, push notifications, in-app purchases, subscription offers, children’s advertising, gaming ads, dark patterns, mobile SDKs, KVKK compliance, influencer integrations, AI-generated content and Advertising Board sanctions.
What Is Mobile Application Advertising?
Mobile application advertising refers to any commercial communication delivered through or in connection with a mobile app. It includes advertisements shown inside the app, advertisements promoting the app itself, and commercial messages sent from the app to the user.
Examples include:
In-app banner advertisements.
Pop-up campaign messages.
Rewarded video ads in mobile games.
Sponsored product placements inside shopping apps.
Push notifications announcing discounts.
In-app subscription upgrade offers.
Personalized product recommendations.
Location-based promotional messages.
Influencer links opening in a mobile app.
Referral code campaigns.
App store promotional screenshots and descriptions.
AI-generated virtual characters promoting products inside an app.
A mobile app advertisement does not need to look like a traditional advertisement. If it influences the consumer’s purchasing decision and serves a commercial purpose, it may be treated as advertising. For example, a “recommended for you” product card inside a shopping app may be advertising if it is sponsored or commercially optimized. A mobile game reward ad may be advertising if it promotes another paid app or product. A push notification may be advertising if it announces a campaign or discount.
The legal assessment focuses on the effect on the consumer, not only the technical form of the message.
General Advertising Law Principles for Mobile Apps
The general principles of Turkish advertising law apply to mobile applications. Advertisements must be truthful, clear, transparent, identifiable as advertising and not misleading. They must not exploit consumers’ lack of knowledge or experience. They must not create unfair commercial practices. They must also comply with sector-specific rules where the advertised product or service is regulated.
This means that mobile app advertisements should not contain false price claims, exaggerated performance statements, hidden fees, fake scarcity messages, unauthorized health claims, misleading environmental claims, undisclosed sponsorships or confusing subscription offers.
The small screen size of mobile devices does not reduce legal responsibility. On the contrary, mobile advertising requires extra care because consumers see limited information at a time. A campaign condition hidden behind several taps may not be sufficient. A tiny disclaimer that is unreadable on a mobile screen may not cure a misleading headline. A countdown timer that creates false urgency may be assessed as manipulative.
Mobile app operators should review the entire user journey: the ad impression, click path, landing screen, product detail page, checkout screen, subscription confirmation, payment button and cancellation process.
In-App Advertising and Transparency
In-app advertisements must be clearly identifiable as advertisements. This is especially important where ads are integrated into the app experience. A sponsored product, paid recommendation or commercial content should not be presented as a neutral platform suggestion unless the commercial nature is clear.
For example, in a shopping app, if a product appears at the top of search results because the seller paid for visibility, the result should be clearly labeled as sponsored or advertised. In a travel app, if a hotel is shown as “recommended” due to commercial placement rather than objective criteria, this should not mislead consumers. In a finance app, if an article promotes a specific loan or investment product, the advertising nature should be clear.
Hidden advertising is prohibited under Turkish advertising law. The Ministry of Trade’s influencer guidance also reflects the same principle by stating that influencer advertisements must be clear, understandable and distinguishable, and that hidden advertising through social media is prohibited. Although that guide is focused on influencers, the underlying transparency principle is relevant for mobile app advertising generally.
Targeted Advertising in Mobile Applications
Mobile apps are powerful tools for targeted advertising because they can collect and analyze user behavior, purchase history, location, device information, app interactions, search history and preferences. This allows advertisers to show personalized ads to specific users or groups.
Under the 2026 amendments, targeted advertising based on consumers’ online behavior and personal data is expressly regulated. The Ministry of Trade states that advertisers may conduct targeted advertising if consumers are provided with direct and easily accessible information about the criteria used to show the advertisement and how those criteria can be changed.
This rule is highly relevant to mobile apps. If an app shows personalized ads based on past purchases, location, browsing behavior, abandoned carts, app usage, demographic data or user profile, the consumer should be able to understand why the ad is shown and how advertising preferences can be changed.
A mobile app should therefore include accessible ad preference settings. These settings should not be hidden in complicated menus. Users should be able to manage personalized advertising choices easily. If the app uses third-party ad networks, SDKs or remarketing tools, the app operator should understand what data is collected and how it is used.
Children and Mobile App Advertising
Children are a specially protected consumer group. Mobile games, educational apps, video apps, toy apps, social media apps and family apps may reach children directly. Children may not fully understand advertising, sponsorship, in-app purchases, virtual currencies or behavioral targeting.
The 2026 amendments introduced a clear rule: targeted advertising directed at children through profiling methods based on personal data is prohibited. This is one of the most important mobile advertising rules for child-facing apps.
A mobile game should not profile children based on gameplay behavior and then target them with personalized paid item offers. An educational app should not use learning behavior to target a child with commercial ads. A video app should not use a child’s viewing habits to serve behaviorally targeted promotions.
Mobile app advertising directed at children should also avoid manipulative messages such as “ask your parents,” “your friends already have this,” “do not miss out,” or “buy now to win.” In-app purchase prompts should be clear and should not pressure children into spending money.
Where apps are likely to be used by children, app operators should apply privacy-protective default settings and avoid profiling-based advertising.
Push Notifications as Advertising
Push notifications are one of the most effective mobile marketing tools. A notification may appear on the user’s lock screen and immediately attract attention. However, push notifications can also be intrusive. If they are used for commercial promotion, they may raise both advertising law and commercial electronic message issues.
A push notification announcing “50% discount today,” “complete your purchase,” “special offer for you,” “upgrade now,” “limited campaign,” or “new product available” is likely to be commercial in nature. The legal treatment may depend on the technical channel and the applicable commercial electronic message rules, but the basic compliance principles are clear: the user should not be misled, the message should be identifiable, and opt-out preferences should be respected.
The Ministry of Trade explains that commercial electronic message rules cover commercial communications sent by electronic means, including SMS and e-mail, and telephone calls. The same framework regulates prior approval, refusal rights and obligations of service providers and intermediary service providers.
Even where push notifications are handled differently from SMS or e-mail in technical terms, businesses should apply a consent-based and preference-based approach. Users should be able to turn off promotional notifications without losing necessary transactional notifications. An order update or security alert should be separated from marketing notifications.
In-App Purchases and Price Transparency
Mobile applications often include in-app purchases. These may include digital items, game currency, extra lives, premium content, subscriptions, filters, training modules, storage space, tokens, virtual goods or service upgrades.
Price information must be clear. A user should understand whether the purchase is one-time, recurring, subscription-based, trial-based or conditional. If a virtual currency is used, the real-money value should not be confusing. If an offer is shown as discounted, the previous price and campaign conditions should be genuine and documentable.
The 2026 amendments include new rules on discount advertising. Conditional sales advertisements providing discounts or other benefits are also subject to discount advertising rules, and the lowest price applied within the last ten days before the discount start date may be presented as the pre-discount price for ordinary goods.
This is relevant for mobile apps that advertise “limited-time discounts,” “special upgrade price,” “premium membership discount,” “first month free,” or “in-app sale.” A false previous price or artificial countdown may create misleading advertising risk.
Subscriptions, Free Trials and Auto-Renewal
Subscription-based mobile apps are common in fitness, education, media, productivity, dating, language learning, finance, entertainment and cloud services. Advertising for subscriptions must be transparent.
A mobile app should clearly disclose:
The subscription price.
The billing period.
Whether the price is monthly or annual.
Whether payment is taken in advance.
Whether the subscription renews automatically.
The cancellation method.
The free trial period.
The post-trial price.
Any commitment or penalty.
A common legal risk is advertising a service as “free trial” while hiding the automatic paid renewal. Another risk is emphasizing “monthly price” while charging annually. A third risk is making cancellation much harder than subscription.
The Ministry of Trade’s 2026 administrative fine announcement states that subscription agreement violations, including information and approval obligations, automatic extension issues and failure to fulfill termination requests within seven days, may be subject to administrative fines per contract or transaction.
Mobile app operators should design subscription screens so that consumers understand the payment obligation before confirming.
Dark Patterns in Mobile App Advertising
Dark patterns are manipulative interface designs that push users toward decisions they might not otherwise make. Mobile apps are especially vulnerable because screen space is limited and design choices strongly influence behavior.
Examples of mobile app dark patterns include:
A large “accept” button and hidden “reject” option.
Pre-selected paid add-ons.
False countdown timers.
Fake stock or availability warnings.
Repeated pop-ups after refusal.
Confusing subscription cancellation paths.
Misleading “continue” buttons that trigger payment.
Hard-to-find privacy settings.
Rewarded ads that do not clearly disclose the condition.
App interfaces must not manipulate consumers into purchases, subscriptions, consent or advertising exposure. A mobile app should make paid actions clear before the user confirms. The user should not be tricked into buying, subscribing, sharing data or accepting advertising cookies.
KVKK, Cookies, SDKs and Mobile Advertising
Mobile advertising often involves personal data processing. Apps may use advertising IDs, SDKs, cookies, pixels, device identifiers, location data, purchase history, usage analytics and behavioral profiles. These practices must comply with KVKK.
The Personal Data Protection Authority’s Cookie Practices Guide explains that necessary cookies may be used for providing information society services, while other cookies may be used for advertising, marketing, functionality and personalization only if explicit consent is given. The guide also provides an example banner where users can accept all, reject all or configure cookie preferences.
Although the guide refers primarily to cookies, the same compliance logic is relevant for mobile SDKs and similar tracking technologies. If an app uses advertising SDKs for behavioral advertising, remarketing or profiling, the app operator should evaluate whether explicit consent is required and whether the user has been properly informed.
A mobile app should not load advertising trackers before obtaining required consent. Consent should be freely given, specific and informed. Users should be able to withdraw consent. Consent records should be preserved.
Location-Based Advertising
Mobile applications can deliver location-based advertisements. A restaurant app may show nearby offers, a retail app may send a discount when the user enters a mall, or a travel app may recommend hotels based on location.
Location-based advertising is legally sensitive because location data may be personal data. App operators should clearly explain whether location is used for advertising, not only for core functionality. If location is not necessary for the service, the user should not be forced to share it for unrelated advertising purposes.
For example, a weather app may need approximate location to provide forecasts, but using precise location for third-party advertising requires separate legal assessment. A shopping app may request location for delivery, but using that data for behavioral advertising should be transparent and lawful.
Location-based push notifications should also be carefully managed. Users should be able to disable promotional location-based messages.
App Store Advertising and Promotional Descriptions
Advertising law applies not only inside the app but also to the way the app is promoted in app stores. App store titles, descriptions, screenshots, promotional videos, ratings, badges and “free” labels may influence consumers.
An app should not be advertised as “free” if essential features require payment and this is not clear. Screenshots should not show features unavailable in the downloaded version. Claims such as “best fitness app,” “guaranteed language learning,” “doctor-approved health app,” “secure investment,” or “earn money easily” should be substantiated and legally reviewed.
App store reviews should not be manipulated. Fake reviews, incentivized positive reviews, employee reviews or AI-generated reviews may mislead consumers. The 2026 amendments introduced rules on consumer reviews, including prohibiting the publication of reviews obtained from platforms where purchase verification is not possible and requiring review categories to be shown clearly where they are separated.
Influencer Promotions for Mobile Apps
Mobile apps frequently use influencers for user acquisition. Influencers may promote apps through referral codes, download links, tutorials, reviews, “day in my life” videos, game streams or discount campaigns.
If an influencer receives payment, commission, free premium access, event participation, discounted services or another benefit, the commercial nature must be disclosed. The Ministry of Trade states that influencer posts must disclose the advertising relationship clearly, visibly and in a manner that consumers can notice at first glance.
The 2026 amendments further require influencer posts involving benefits such as earnings, discounted goods or services or event participation to use wording such as “advertisement” or “promotion” so that the advertising nature is clearly understood.
Mobile app advertisers should give influencers approved disclosure wording and prohibit misleading claims. An influencer should not say “I earned money easily with this app,” “this app guarantees success,” or “this app is risk-free” unless such claims are lawful and substantiated.
Mobile Game Advertising and Rewarded Ads
Mobile games often rely on rewarded ads, in-app purchases, virtual currency, loot-style mechanics, limited-time offers and cross-promotions. These practices require careful legal review, especially when children are likely to use the game.
Rewarded ads should clearly explain what the user receives after watching the advertisement. If an ad offers coins, extra lives or unlocks, the condition should be clear. The user should not be misled about whether the reward is free, temporary or tied to further purchases.
In-app purchase prompts should not exploit children’s vulnerability. Virtual currency should not obscure the real cost. Limited-time offers should not be fake. Countdown timers should reflect real campaign periods. If a game uses personalized purchase prompts based on user behavior, targeted advertising and personal data rules should be assessed.
For children, profiling-based targeted advertising is prohibited under the 2026 amendments. This is especially important for mobile games.
AI-Generated Mobile App Advertisements
Mobile apps increasingly use AI-generated avatars, chatbots, virtual influencers, synthetic voices, recommendation agents and personalized promotional messages. AI can create legal risk where consumers believe that an artificial character is a real person or that a real person has personally recommended a product.
The 2026 amendments require clear disclosure where advertisements use AI-generated digital characters that cannot be distinguished from real humans. They also prohibit advertisements where an AI-generated digital copy of a real person creates the impression that the person personally experienced or recommended a product or service.
In mobile apps, this may apply to virtual shopping assistants, AI fitness coaches, AI financial guides, AI tutors, AI doctors, synthetic influencers and AI-generated testimonials. If the character is promotional, the advertising nature and artificial nature should be clear where required.
Sector-Specific Risks for Mobile Apps
Some app categories require stricter advertising review.
Health and fitness apps should avoid medical diagnosis, treatment or cure claims unless legally permitted. Food supplement apps should not present supplements as medicines. Cosmetics apps should not promote products as disease treatments. Financial apps should not promise guaranteed profit or risk-free investment. Education apps should not guarantee exam success unless such claims are provable. Dating apps should not use fake profiles or misleading user availability claims.
Children’s apps should avoid manipulative advertising, profiling-based targeted ads and unclear in-app purchases. Gambling, illegal betting and illegal games of chance are high-risk areas; the 2026 amendments expanded advertising prohibitions concerning illegal games of chance.
A mobile app should be reviewed according to its sector, not only according to general advertising rules.
Distance Sales and Mobile App Transactions
When goods or services are purchased through a mobile app, distance sales rules may apply. The Ministry of Trade’s distance sales guidance states that intermediary service providers are jointly responsible with sellers or providers for pre-information, confirmation and proof, and that they may be responsible for consistency between platform advertisements/promotions and mandatory pre-contractual information.
This is highly relevant for mobile marketplaces, food delivery apps, travel apps and service platforms. If an app advertisement promises free cancellation, fast delivery, discount, refund, warranty or special service, the pre-contractual information and final transaction terms should match the advertisement.
If the app interface hides material information until after payment, the practice may create consumer law risk.
Advertising Board Sanctions
Unlawful mobile app advertisements may lead to Advertising Board sanctions. These may include suspension, correction, administrative fines, temporary suspension and access blocking for online content.
For 2026, administrative fines for misleading advertisements and unfair commercial practices may range from 99,339 TL to 39,916,524 TL, depending on the nature of the violation, benefit obtained, harm caused, fault, economic condition of the violator and advertising medium.
Mobile app operators may also face additional risks under distance sales rules, subscription rules, commercial electronic message rules and KVKK. If an app operates as an intermediary platform, failure to establish systems allowing consumers to submit and track requests may lead to a significant administrative fine; for 2026, the Ministry announced this amount as 6,380,408 TL.
Therefore, mobile app advertising compliance should be treated as a serious legal risk management issue.
Practical Compliance Checklist for Mobile App Advertising
Businesses operating mobile applications in Turkey should apply the following checklist:
Identify all commercial messages inside the app.
Clearly label sponsored content and paid placements.
Do not present ads as neutral recommendations.
Provide transparency for targeted advertising criteria.
Do not conduct profiling-based targeted advertising directed at children.
Separate transactional notifications from marketing push notifications.
Obtain valid consent where required for promotional communications.
Provide easy notification preference controls.
Disclose subscription price, renewal, trial and cancellation terms clearly.
Avoid false discounts and artificial countdown timers.
Do not use pre-selected paid add-ons.
Ensure in-app purchase prices are clear.
Review mobile SDKs, advertising IDs and tracking technologies under KVKK.
Obtain explicit consent where required for advertising and marketing trackers.
Make rejection of non-essential tracking as easy as acceptance.
Review app store descriptions, screenshots and promotional videos.
Avoid fake reviews and manipulated ratings.
Ensure influencer promotions are clearly disclosed.
Review AI-generated characters and testimonials.
Apply stricter rules for children, health, finance, food supplements and cosmetics.
Preserve screenshots, campaign records, consent logs and ad settings.
Best Practices for Mobile App Developers and Advertisers
Mobile app advertising compliance should be built into product design. Legal review should not occur only after the app is ready for launch. Product managers, UX designers, marketing teams, data protection officers and legal counsel should work together.
A mobile app should have separate settings for privacy, advertising personalization, push notifications and subscription management. The user should not be forced through confusing interfaces. Paid offers should be clearly marked. Cancellation should be easy. Promotional notifications should be controllable.
App developers should also audit third-party SDKs. Many apps include advertising SDKs that collect data for purposes the app operator may not fully understand. Since the app operator may remain responsible for data processing and advertising practices, SDK governance is essential.
For high-risk sectors such as health, finance, children’s apps and gaming, legal review should be stricter and more frequent.
Conclusion
Advertising law for mobile applications in Turkey is a rapidly developing compliance field. Mobile apps are not only software products; they are advertising channels, sales channels, data collection environments and consumer interfaces. In-app ads, push notifications, personalized recommendations, subscriptions, rewarded ads, influencer links, AI-generated characters and app store descriptions may all be subject to Turkish advertising law.
The 2026 amendments to the Regulation on Commercial Advertising and Unfair Commercial Practices strengthen consumer protection in digital markets, especially in targeted advertising, children’s profiling, AI-generated advertisements, influencer promotions, discount advertising and consumer reviews. These changes are particularly relevant for mobile apps because apps often combine personalization, behavioral data, push notifications and in-app purchase design.
KVKK compliance is also central. Advertising and marketing trackers, cookies, SDKs and personalization technologies may require explicit consent and proper information. The KVKK Cookie Practices Guide makes clear that advertising and marketing cookies are linked to explicit consent-based use in its good-practice example, while necessary cookies are treated separately.
For businesses operating mobile applications in Turkey or targeting Turkish consumers, the safest approach is transparency by design. Ads should be recognizable. Prices should be clear. Subscriptions should be understandable. Push notifications should respect preferences. Children should not be profiled for targeted ads. AI-generated characters should not create false human experience. Personal data should not be used for advertising without proper legal basis.
A compliant mobile app advertising strategy protects consumers, reduces regulatory risk and strengthens long-term brand trust. In Turkey’s digital market, mobile advertising success should not depend on manipulation, hidden tracking or confusing design. It should depend on lawful, transparent and fair communication.
