Privacy Policy

Last updated: 23 September 2026

This policy explains how Yieldra handles your information. The app is provided by Volkan Günay (Vomcore). Contact: hello@vomcore.com.

Short version

No account, no sign-up, no advertising, no analytics SDK and no AI service. Yieldra has no server of its own and does not use the camera, your photos, your location or your contacts. Every calculation happens on your iPhone; the only network use is verifying purchases.

What is stored on your device

• Registers: the values in the TVM registers.
• Tape: the last 200 lines of your calculations.
• Saved problems: the problems you choose to save.
• Worksheets: the inputs you entered on each worksheet.
• Preferences: the number of decimal places, and whether you have finished the first-run screens.

None of this leaves the device. Deleting the app removes all of it.

Payments

Yieldra Pro is sold as a weekly, monthly or yearly subscription, or as a one-time lifetime purchase. Purchases are handled by the App Store and we never see your payment details. Whether your purchase is active is verified through RevenueCat, Inc. using an anonymous identifier that contains no name, email, calculation data or advertising ID.

What we do not do

No advertising SDK, no analytics SDK, no tracking pixel, no fingerprinting, no data broker, no tracking across apps. We do not sell or share your data.

Children

Yieldra is not directed at children under 13 and does not knowingly collect personal information from them.

Your rights and contact

We hold no account and no personal profile, so there is nothing on our side to access or delete; your data is on your device and deleting the app removes it. For any question, write to hello@vomcore.com.

Changes

If this policy changes, the date at the top changes with it and the new text is published here before the version that relies on it ships.
