ViralZ Privacy Policy

Last updated: October 25, 2026

1. Who we are

This Privacy Policy explains how FEYY PROJE MÜHENDİSLİK LİMİTED ŞİRKETİ ("FEYY", "we", "us") collects, uses, stores and protects your personal data when you use the ViralZ mobile application (the "App").

FEYY is the data controller for the App.

• Address: Yenigün Mah. Mevlana Cad. B Blok No: 54 B İç Kapı No: 502, Muratpaşa / Antalya, Türkiye

• Email: support@feyy.com.tr

ViralZ helps creators understand how their TikTok and Instagram content performs. It also gives AI-generated ideas, scripts and feedback.

2. Data we collect

2.1 Data you give us

• Social account handles. When you connect a TikTok or Instagram account, you type its public username. We do not ask for your TikTok or Instagram password, and we do not log in to your social accounts.

• Your answers in the App. This includes onboarding answers (for example your goals, niche, language and posting habits) and the messages you send to the AI coach.

• Content you upload. This includes photos and videos you choose to send for analysis, and links you paste.

The App has no email or password sign-up and no Apple or Google sign-in. We identify your account with a random identifier that is created on your device.

2.2 Public social media data

When you connect an account, we collect publicly available data about it through third-party data providers. This includes:

• profile information;

• follower counts;

• public posts and videos, with their captions and thumbnails;

• view, like, comment and share counts;

• public comments.

We also read public trending content in your niche to build trend reports.

2.3 Data collected automatically

• Device and app data: device model, operating system version, app version, language, time zone and a random app identifier.

• Usage data: the screens you open, the features you use and in-app events.

• Crash and performance data: crash logs and diagnostics.

• Push notification token: collected if you allow notifications.

• Advertising identifier (IDFA): collected only if you allow tracking in the iOS App Tracking Transparency prompt. You can change this at any time in iOS Settings.

2.4 Purchases

Subscriptions and credit packs are processed by Apple. We do not see or store your payment card details. We receive the purchase status and transaction identifiers so that we can give you access and credits.

3. How we use your data

We use your data to:

• analyze your public content and show you performance insights;

• generate AI ideas, scripts, plans and coaching answers for you;

• run your account, credits and subscription;

• send you notifications you allowed, such as "your analysis is ready";

• keep the App secure, fix bugs and improve features;

• measure our marketing campaigns, if you allowed tracking.

4. Artificial intelligence

ViralZ uses third-party AI models to create insights, ideas, scripts, images and coach answers.

What we send to AI providers:

• your public profile and post data;

• your onboarding answers;

• your messages to the coach;

• photos and videos you upload for analysis.

Who the AI providers are:

• Google (Gemini models, through Google Cloud Vertex AI and the Gemini API);

• Anthropic (Claude models);

• OpenAI;

• OpenRouter, which routes requests to the model providers above.

Limits on what we share and how it is used:

• We send only the data needed for the feature you use.

• We do not send your password, payment data or advertising identifier.

• The providers process this data on our behalf, under their API terms. Under those terms, data sent through their APIs is not used to train their models.

Before your first AI analysis, the App asks for your consent. AI output can be wrong or incomplete. It is for information only and does not guarantee views or income.

5. Who we share data with

We do not sell your personal data. We share data only with service providers that help us run the App:

• Cloud hosting and database: Google Cloud / Firebase (Firestore, Cloud Storage, Cloud Functions, Firebase Cloud Messaging for push notifications, Firebase Crashlytics for crash reports).

• AI providers: listed in section 4.

• Social media data providers: third-party API providers that return public TikTok and Instagram data.

• Purchases: Apple and RevenueCat, which manage subscriptions and purchase status.

• Analytics: Amplitude, which receives product usage events.

• Marketing attribution: Adjust, Meta (Facebook SDK) and TikTok (TikTok Business SDK). They measure which campaigns bring users. They use your advertising identifier only if you allowed tracking.

We may also disclose data:

• if the law requires it;

• to protect our rights;

• as part of a merger or sale of the business.

6. International transfers

FEYY is based in Türkiye. Our service providers may process data in other countries, including the United States and the European Union.

Where the law requires it, we use appropriate safeguards for these transfers, such as standard contractual clauses.

7. How long we keep data

• Account data, analyses and AI history: kept while your account is active.

• Photos and videos you upload to the AI coach: deleted automatically within 7 days.

• Deleted account: deleted when you delete it. We keep only the purchase and credit records the law or fraud prevention requires.

8. Your rights

Depending on where you live, you may have these rights. They include rights under KVKK (Türkiye) and the GDPR (EU):

• access your data;

• correct it;

• delete it;

• restrict or object to processing;

• data portability;

• withdraw consent.

How to exercise them:

• Delete your account in the App: Settings → Delete account. This removes your account, connected accounts, analyses and AI history.

• Disconnect a TikTok or Instagram account: in Settings.

• Turn off tracking or notifications: in iOS Settings.

• Any other request: email support@feyy.com.tr.

You can also complain to your local data protection authority. In Türkiye, this is the Kişisel Verileri Koruma Kurumu.

9. Security

We use encryption in transit, access controls and the security features of our cloud providers. No system is 100% secure, so we cannot guarantee absolute security.

10. Children

The App is not for children under 13, or under the minimum age in your country. We do not knowingly collect data from children. If we learn that we have, we delete it.

11. Changes

We may update this policy. We will change the "Last updated" date. If the change is important, we will tell you in the App.
