Privacy Policy
- 01
Who we are
Percent & Finance Calc Pro (version 2.1) is published by denix.studio, founded by Gökhan Alp Atar, Nilüfer / Bursa, Turkey. This policy describes this app specifically — our other apps handle data differently and each has its own policy.
- 02
How Percent & Finance Calc Pro handles data
Percent & Finance Calc Pro runs entirely on your device. Calculations, history and saved results stay on the phone; there is no account and no server.
- 03
What is collected
Percent & Finance Calc Pro may hold the figures you type and the calculations you choose to save to history, with any notes you add; favourite calculations, starred calculations and a count of how often you open each one, used only to show your most used calculations; an optional name, company name and company logo you enter during setup, shown on your results; language, theme and number-format preferences; your purchase status, which Apple provides to the app to unlock Pro; and anonymous crash reports if iOS is set to share them with developers.
- 04
Why
Data is used only to make Percent & Finance Calc Pro work as described on its App Store page, to fix crashes and to keep the app secure. It is never sold, rented, or used to build an advertising profile.
- 05
Permissions this app asks for
Percent & Finance Calc Pro asks for no system permissions: no location, no camera, no photo library, no contacts, no microphone.
- 06
Third parties
Percent & Finance Calc Pro uses no advertising networks, no third-party analytics SDKs and no external processors. Nothing is shared with anyone.
- 07
Retention and deletion
Calculation history can be cleared inside the app at any time and disappears entirely if you delete the app. Because there is no account and no server, we cannot see, restore or hand over your content — it is not ours to hold.
- 08
Security
Data held on the device is protected by iOS app sandboxing and file-level encryption. Where information does travel, it travels over TLS. No system is perfect, but we keep the amount of data involved as small as the app allows.
- 09
Children
Rated 4+. The app is a general-audience calculator and does not knowingly collect personal information from children under 13.
- 10
Your rights (GDPR and KVKK)
You may ask for access to any personal data we hold about you, ask for it to be corrected or deleted, object to processing, ask for portability, and withdraw consent. Where the app holds everything on your device, you exercise those rights directly: edit or delete the content in the app, or delete the app. Write to us and we answer within 30 days.
- 11
Payments
The app is free to download with no advertising. Pro is offered as a monthly or yearly auto-renewing subscription (the yearly plan may include a free trial for eligible new subscribers) or as a one-time lifetime purchase. Payment is charged to your Apple ID; subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled in your Apple ID account settings. All purchases are processed by Apple; we never see your card details.
