Overview
ZingRead collects only the data needed to run the service. The books, PDFs and personal texts you upload stay on your device and are never sent to our servers. If you create an account, your progress data (WPM history, sessions, lessons, badges, settings) is stored on our servers, encrypted in transit (TLS), so it can sync across your devices. You can use the app without an account; an anonymous identifier is then created for you and your progress and usage data are stored under it, without your name or email.
This policy applies to the ZingRead mobile apps (iOS, Android) and the zingread.com.tr website.

No cookies; IP addresses are not written to our database |
We don't share your data
We don't sell, rent, or share your data with ad partners, data brokers, or third parties. We only use:
- Supabase: hosting of account and progress data (EU — Frankfurt). Only your own account can access your data.
- RevenueCat: verifies the status of your Premium subscription; payment details stay with Apple or Google.
- Apple / Google: sign-in (Sign in with Apple, Google), payments and notifications — subject to their own privacy policies.
- Sentry: crash and error reports. Your name, email and IP address are not included.
We don't share data for advertising and we don't track you across devices. In-app usage data is reviewed only by us, on our own server (Supabase, EU); we use no third-party analytics service. Our website uses no cookies; it keeps cookieless visit statistics on our own server, as described below.
Website visit statistics
We don't use cookies on zingread.com.tr and we don't store any identifier on your device. To see how the site is used, each visit sends the coarse details listed in the table above to our own server (Supabase, EU — Frankfurt). So that visits on the same day can be linked, your IP address and browser details are turned into a summary using a secret key that is generated at random each day and deleted the next; once the key is gone, nobody, including us, can link that summary back to you, and the next day the same visitor appears under a different summary. The IP address itself is never written to our database; it may only remain for a few days in our hosting provider's security access logs. This data is never combined with your app account, never shared, and is deleted after 12 months.
We do this on the basis of our legitimate interest in running and improving the site (KVKK Art. 5/2-f, GDPR Art. 6(1)(f)). If Global Privacy Control is turned on in your browser, nothing is sent.
Your rights
Under KVKK and GDPR you have the right to access, correct, delete and export your data. You can delete your account inside the app via Settings › Account › Delete Account; your data is removed from our servers immediately and from backups within 30 days. Local data can be cleared via Settings › Reset Progress.
Changes
When we make a material change to this policy we show a notice in the app and update the date on this page.
