Privacy Policy
Last updated: 19 July 2026
In short: Sıfırla collects no data from you. It never asks for an account, email or bank connection. Everything you enter stays only on your own device and never reaches us.
1. What data do we collect?
None. Sıfırla has no server and collects, stores or transmits no personal data. Using the app requires no name, email, phone number or any other identifier.
2. Accounts and authentication
You do not need to create an account. There is no sign-up, sign-in or email verification. The app creates no identifier that could identify you.
3. Analytics, trackers and cookies
Sıfırla does not use analytics tools, trackers, cookies, advertising IDs or fingerprinting. This website contains no third-party cookies, tracking pixels or external scripts either. Your browser's local storage may be used only to remember your preferences (theme and language); that information never leaves your device.
4. Where is your debt data stored?
All debt information you enter (balances, interest, due dates, etc.) is kept only in your device's browser local storage. It stays on your device and is never sent to the developer, to us, or to any third party.
5. Backups
If you want to back up your data, the app creates a single file that you download to your own device. This file is not sent to us; where you keep it and who you share it with is entirely under your control. The developer cannot access it.
6. Deleting your data
You can delete your data in two ways: from within the app via More → "Delete all my data", or by uninstalling the app / clearing your browser's site data. Because the data lives only on your device, deletion is fully in your hands; we hold no copy to delete. For a step-by-step guide, see Deleting Your Data.
7. Sharing with third parties
Since no data is collected, no data is shared with third parties. We do not sell, rent or use your data for advertising.
8. Children's privacy
Sıfırla is not directed at children and knowingly collects no data from children. Because no data is collected from anyone, the app offers the same privacy guarantee to users of every age.
9. Your rights (KVKK / GDPR)
Under GDPR and Turkey's KVKK (Law No. 6698 on the Protection of Personal Data), you have rights such as access, rectification, erasure and portability of your data. Because Sıfırla processes, stores or transfers none of your personal data, these rights are guaranteed by design: you access all data directly on your own device, and you can edit, export or permanently delete it at any time. Since we process no data, there is no access or erasure request to send to us.
10. Changes
We may update this policy from time to time. When we do, the "Last updated" date above will change.
