1. Data controllers
Schools. A school is the data controller for the student, guardian and staff data it enters in Petek. Onore processes that data on the school's behalf, on its instructions and under its contract with the school (Law Art. 3(1)(ğ)). Onore's authorised staff may access a school's account only for support and operations and for a limited time; that access and every action during it is written to the school's audit log, which the school can see.
Onore. Onore, the developer of Petek, is the data controller for: what you send through the demo, quote, sales and contact forms on petek.school; the site chat assistant's records; the sign-in and security data of Petek user accounts (sessions, two-step verification, security logs); support requests; and ad measurement in the iPhone and iPad app.
Onore is the trade name of Kaan YILDIZKAN's sole proprietorship. Onore's details:

5.1 AI assistant
Petek's AI assistant and receipt reading send the question, any attached photo or receipt and only the school data within the asking person's permissions to the AI provider chosen in the school's settings. If the school entered its own API key the request goes through the school's account, otherwise through Petek's.
Requests that read school data, carry a photo or file, or contain a phone number, e-mail or Turkish ID number count as personal data and by default go only to Anthropic, OpenAI and Google. Personal data goes to Alibaba Qwen or DeepSeek only if the school owner turns on that provider under Assistant settings › Personal data (KVKK); only the owner can change it and every change is recorded. If no suitable provider is left, nothing is sent; if the school turned on masking, the text is sent with names and contact details masked, and photos and files are then not sent.
The iPhone and iPad app shows what goes where and asks before the assistant or receipt reading is first used; without permission nothing is sent, and the permission can be withdrawn at any time. The chat assistant on this site never reaches any school's data; if your message contains a name, phone, e-mail or Turkish ID number it is not sent to the AI.
As data controller, the school decides whether to use the assistant, which provider and whether to allow personal data. Because the providers' servers are abroad, this is a regular transfer abroad: the provider's own data processing agreement alone is not enough, and the standard contract announced by the Board is required under Art. 9(4)(c) (see 5.3). Onore does not use or sell this data for advertising; retention on the provider's side follows the provider's policy.
5.2 Ad measurement in the iPhone and iPad app
Petek's iPhone and iPad app (the staff app) contains the Meta Platforms Ireland Ltd. SDK and Google Ireland Ltd.'s Google Analytics for Firebase. The purpose is ad measurement: knowing which ad brought someone to the app. The app shows no ads. The data sent is listed in the table in section 2; the advertising identifier is sent only if you allow App Tracking Transparency on iOS. Your name, e-mail, phone and any student or guardian data are never sent to Meta or Google.
The legal ground for this processing is explicit consent. The transfer abroad, however, relies on the standard contract under Art. 9(4)(c), not on consent (see 5.3); since the 2024 amendment consent supports only occasional transfers. You can turn measurement off in the app under Menu › Profile › Privacy › Ad measurement and on the iPhone under Settings › Privacy & Security › Tracking. Petek Aile (the parents' app) contains neither kit.
5.3 Transfers abroad
Some of the providers above have servers outside Türkiye. These transfers follow Article 9 of the Law: for regular transfers to countries without an adequacy decision, the standard contract announced by the Personal Data Protection Board is signed and notified to the Authority within five business days of signature (Art. 9(4)(c) and 9(5)).
Status of the standard contracts: ⟨being updated⟩
6. Retention
| Data | Period |
|---|---|
| Demo, quote and contact forms | 2 years after the request is closed |
| Account data | While the account is open; at once when it is deleted, and from backups within 30 days |
| Session and security logs | 1 year(s) after the session ends |
| Site chat records | 2 years, with personal details masked |
| School data | The period the school sets and the law requires |
Data whose period has ended is deleted, destroyed or anonymised.
