Subsi privacy addendum

Last updated: 7 November 2026

This addendum is part of the Yelkovan Privacy Policy and covers what is specific to the Subsi app. The data controller, your rights and how to contact us are in the main policy.

1. Publisher

Subsi is developed and published by Yelkovan (Yiğit Özdemir). The app's technical ID is com.ay.subsi; the data folder on your phone is named "abonem" after the app's earlier working name.

2. Where your data is

Your subscriptions, bills, spending, income, cards, loans, budgets, savings, goals and settings are kept in a single file in the app's own storage on your phone. On iPhone, the app's shared container (App Group) is also used for widgets and the Share extension; on Android, widgets read from the app's own storage. We cannot access this data.

If your phone's own backup (iCloud or Google) is on, the operating system may include the app's data in it. That backup is in your account and follows your settings; we cannot access it.

3. Internet

Subsi makes no network requests. The Android version does not even have the internet permission. You enter exchange rates yourself; the app never fetches rates, prices or anything else from the internet. The privacy and support links in Settings open in your browser.

4. Screenshots, PDFs and Share

When you pick an image or a file, or send one to Subsi from the Share menu, its text is read on your phone: on iPhone with Apple's Vision and PDFKit frameworks, on Android with Google's on-device text recognition library ML Kit and Android's PDF renderer. The ML Kit model ships inside the app; since the app has no internet permission, it cannot send anything.

You choose photos with the system picker; the app does not scan your library. Copies made for reading are deleted once read. Items received through Share wait under "Shared with Subsi" until you read or delete them. A PDF password is used only to open that PDF and is not stored.

5. Reminders

Renewal, bill, card due date and other reminders are scheduled and shown on your phone. Nothing is sent anywhere for this. You grant the notification permission and change the time and types in Settings.

6. Widgets

If you add widgets, summary information such as upcoming payments, amounts and subscriptions is written where the widget can read it. Widgets appear on your Home Screen (on iPhone also on the Lock Screen), so anyone who sees your phone can see those amounts. If you'd rather not, don't add widgets or remove them.

7. Backup and export

A backup or CSV file is created only when you ask for it, and you choose where it goes (files, email, cloud). These files are not encrypted; keep them somewhere you trust. When you restore, the file you choose is read only on your phone.

8. Purchase

Subsi is a one-time purchase made through the App Store or Google Play. We never see your payment details. There are no in-app purchases or subscriptions.

9. What we don't use

• No ads, advertising ID or tracking; on iPhone you are never asked for tracking permission.
• No analytics or crash reporting software (SDK).
• No account, sign-in or server.
• The app does not access your location, camera, microphone or contacts.
• We don't sell or share your data; it never reaches us.

10. Deletion

Settings › Erase all data deletes all your records from the phone; this can't be undone. Deleting the app from your phone also deletes its data (except your phone's own backup).

11. Contact

Questions: info@yelkovan.ai. When you write to us, we use your email address only to reply. If this addendum changes, the new version is published on this page.
