PFA CalculatorPrivacy Policy
Last updated: 9 November 2026
PFA Calculator: Navy PRT & BCA is an app from Itworked Systems, a company registered in Türkiye. This page explains what the app does with information.
Itworked Systems is responsible for the app under Turkish data protection law (KVKK, Law No. 6698) and, for users in the EU and the UK, the GDPR.
- Everything you enter (age, sex, test results, height, waist, weight) and your saved history stays on your phone, in the app's local storage. It is never sent anywhere.
- No account, no sign-in, no ads, no analytics SDK and no tracking. The calculators work without an internet connection.
- The only network service is Adapty, which handles purchases of PFA Calculator Pro.
- We never sell your information.
What leaves your phone, and why
| What | Why | Who receives it |
|---|---|---|
| An anonymous Adapty profile ID, the device and app identifiers needed for purchases, your purchase history, and a one-time tag saying whether the install comes from the App Store or Google Play, or is a test build | To unlock PFA Calculator Pro, restore it on a new phone, and tell store installs from test builds | Adapty (Adapty Tech Inc.), which checks purchases for us, and Apple or Google, which take the payment. We never see your card details |
That is all. This data is not linked to your identity and is not used for tracking or ads. The app turns off Adapty's IP address collection and its advertising ID collection, does not ask to track you, and never sends Adapty your age, sex, test results, height, waist, weight or history. Your connection's IP address is necessarily seen by Adapty's servers to deliver the request, but the app tells Adapty not to collect it. Read how Adapty handles this data at adapty.io/end-users-privacy.
Why we may use this data
To deliver what you bought, and to keep purchases working across devices. Nothing else is done with it.
How long it is kept
- On your phone: your entries, saved results and settings stay until you delete them or the app.
- Purchase records are kept by Adapty for us so Pro can be checked and restored, and by Apple or Google under their own rules.
Where the data is processed
Adapty is based outside Türkiye and may process data in other countries, including the United States. These transfers follow the rules for sending data abroad in Turkish data protection law and, for users in the EU and the UK, the GDPR.
App stores and links
Apple and Google run the stores you download the app from, and may collect information about downloads and crashes under their own privacy policies. The app links to this website and to the official publications it uses; if you open those links, your browser visits those websites like any other. On itworkedsystems.com our host Cloudflare processes the request to deliver the page. We run no analytics on these pages.
Your rights
Under Turkish data protection law (KVKK, article 11) and the GDPR you can ask whether we process data about you, and ask for access, correction or deletion. We hold almost nothing ourselves. To ask for deletion of the purchase records kept for this app, email us the anonymous purchase ID shown in the app on the More tab, so we can find them. If you email us, we use your message only to answer it and delete it when it is no longer needed. You can also complain to Türkiye's Personal Data Protection Authority (Kişisel Verileri Koruma Kurumu) or, if you live in the EU or the UK, to the data protection authority where you live.
Children
The app is not made for children under 13, and we do not knowingly process their data.
Changes
If the app ever starts using data in a new way, we will update this page and the date at the top before that version is released.
