Privacy Policy
Last Updated: 1 October 2025
1. Introduction
Welcome to PekiBook’s Privacy Policy. Your privacy is important to us. This policy explains what information we collect, how we use and share it, and your rights regarding that information. We are committed to handling your personal data transparently, securely, and in compliance with applicable privacy laws, including the EU General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA) as amended by the CPRA, Turkey’s Law on Protection of Personal Data No. 6698, and other relevant regulations.
By using the PekiBook mobile app or website (collectively, the “Service”), you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree with our practices, please do not use the Service. We encourage you to read this document carefully and contact us if you have any questions.
Data Controller: For the purposes of data protection laws, the “data controller” (the party responsible for your personal information) is Erenay Kaya, the developer of PekiBook, located in Turkey. You can find our contact details at the end of this policy.
This policy applies to all users of PekiBook worldwide. However, certain provisions apply specifically based on your location (for example, additional rights for EU/EEA users or California residents). We will highlight those where relevant.
2. Information We Collect
We collect several categories of information from and about users of PekiBook. The types of personal data we collect depend on how you interact with the Service. Generally, the information falls into these categories:
Information You Provide Directly:
-
Account Information: When you create an account, we may collect identifiers such as your name, email address, username, profile photo (if you choose to add one), and login credentials. If you sign in via a third-party platform (like “Sign in with Google” or “Sign in with Apple”), we receive basic account information from them (e.g., your name and email) as permitted by that service’s privacy settings.
-
Profile and Learning Data: You may provide additional information within the app, such as your language proficiency level, learning goals, or settings/preferences (e.g., interface language, notification preferences). This also includes data about your progress, such as completed "Daily Deeds," "Unit Deeds," and achievements unlocked in the "Glory Gallery," which we record to track your progress and provide a backup of your accomplishments.
-
Content and Submissions: Any content you submit through the Service, including your answers to exercises and "homework" questions, feedback, or support inquiries. When you submit answers, they may be stored on our servers and sent to our third-party AI provider to evaluate whether they are correct. We analyze this data to improve our lessons and for backup purposes. Please avoid sharing sensitive personal information in your submissions.
-
Game and Activity Data: If you participate in in-app games, we collect and store your scores, the number of coins you collect, the amount of gems you have, and records of virtual items you purchase, such as backgrounds and skins. This information is necessary to operate the game features and save your progress.
-
Payment Information: If you subscribe to PekiBook Premium, purchase gems from the "Peki Market," or make other purchases, our third-party service providers process the transaction. All purchases in the iOS or Android apps are processed by Apple or Google respectively; we do not receive your full credit card number or billing information. We use a subscription management service (RevenueCat) which receives purchase tokens/receipts from the app stores to confirm your purchase, manage your subscription status, and provide us with analytics. We may receive confirmation of your purchase, subscription status, and limited information like an order ID or an email, which we keep for our records.
-
Communications: If you contact us directly (via email, support chat, or phone), we will receive your name, email, and the contents of your message or attachments, as well as any other information you choose to provide.
Information We Collect Automatically:
When you use PekiBook, we (and service providers acting on our behalf) automatically collect certain information about your device and usage of the Service through cookies, SDKs, and similar tracking technologies. This may include:
-
Device Identifiers: Such as your device model, operating system version, unique device IDs (for example, IDFA for iOS or Android Advertising ID, if available), device language, and device region.

We receive purchase confirmation data from app stores (Apple, Google) and our subscription management provider (RevenueCat) to validate and manage your subscriptions and in-app purchases.

We may receive aggregate, de-identified demographic or interest information about our user base from advertising or analytics partners.
