Termwise Privacy Policy
Last updated: November 10, 2026
Summary
Termwise does not require an account, shows no ads and does not track you across apps or websites. Your study progress stays on your device.
Who we are
Termwise is developed and published by Memet Dursun Çelenk, an individual developer publishing apps under the name cmdappstudio ("we", "us"). We are responsible for the data described in this policy. Contact: hello@cmdappstudio.com, Zümrütevler Mah., Maltepe, İstanbul, Türkiye.
Data stored on your device
Your study progress (flashcard history, quiz scores, lessons read), your settings and your recent decoder searches are saved only on your device. They are not sent to us. You can erase them at any time with Settings > Reset progress, or by deleting the app.
Purchases
Payments are processed by Apple; we never see your payment details. To unlock and restore Pro we use RevenueCat, which receives an anonymous app user ID, your purchase history and basic technical information (such as app version, iOS version and App Store country). This information is used only to provide and restore your purchases. It does not include your name or e-mail address.
Optional usage data
Sharing anonymous usage data is off by default. Only if you turn on "Share anonymous usage data" in Settings, the app sends usage events to Google Analytics for Firebase so we can see which features are used and improve the app.
These events record: which screens and chapters you open; when you finish a lesson, a flashcard session, a word-building round or a chapter quiz, with the chapter and your score or number of cards; when you decode a term; when you play a pronunciation; when you change your spelling setting or reset your progress; and when you open the upgrade screen, when a purchase starts, completes, is canceled or fails, and when you restore purchases, with the plan chosen. Your spelling setting (American or British) and whether Pro is active are also included. Google Analytics also measures app opens, sessions and in-app purchases (the product and its price) on its own.
The app never sends text you type. When you decode a term, the term itself is sent only if it is one of the app's own dictionary terms; for anything else, only the number of word parts is sent.
With these events, Google Analytics records basic technical information such as your device model, iOS version, app version and a general location (country, region or city) that Google works out from a masked IP address. The events are tied to a random identifier for this installation of the app, not to your name, e-mail address or Apple Account. The app does not collect the advertising identifier, and the advertising features of Google Analytics are turned off.
You can turn usage data off at any time in Settings. After that, no further events are sent.
On-device features
Pronunciation uses the speech voice built into your device, and the term decoder runs entirely offline. The app does not access your camera, microphone, photos, contacts or your device's location services.
Third-party services
The only third parties that receive data from the app are Apple (payments), RevenueCat (purchase management) and, only if you opt in, Google (Google Analytics for Firebase, anonymous usage data). They process this data to provide their service to us under their own privacy policies and data processing terms, which require them to protect it. We do not share data with anyone else.
Sharing and selling
We do not sell your data, do not share it with advertisers and do not use it to track you.
Data retention and deletion
Data on your device is kept until you reset your progress or delete the app.
Purchase records are kept by Apple and RevenueCat for as long as needed to provide and restore your purchases and to meet legal and accounting obligations. Optional usage data is kept by Google Analytics only for the limited retention period set for our project and is then deleted automatically.
You can ask us to delete any data we hold about you, or ask what we hold, by writing to hello@cmdappstudio.com. Because this data is anonymous, we may ask for information that lets us find it, such as the date of a purchase.
Your choices
You can withdraw consent to optional usage data at any time by turning it off in Settings. Depending on where you live, you may have additional rights under local law, such as the right to access, correct or delete your data or to complain to a data protection authority.
Children
Termwise is a study aid for students and is not directed to children under 13. We do not knowingly collect personal information from children.
Changes and contact
If this policy changes, the updated version will be published on this page with a new date. The app links to this page from Settings. If you have any questions about this policy, write to hello@cmdappstudio.com.
