Oathway privacy policy
Last updated: October 26, 2026
This policy explains what information the Oathway app uses and why. Oathway is made by Devrim Çatak ("devca", "we"), who is responsible for the processing described here.
The short version
- Oathway has no account and no sign-up. We don't ask for your name, email or phone number.
- What you enter in the app (your language, test version, state and representative, interview date, study progress, test history and settings) stays on your phone. We never receive it.
- The free version shows ads from Google AdMob. Personalised ads are only shown if you agree.
- We use Google Firebase to see how the app is used and to fix crashes.
- We don't sell your personal information.
Information stored on your phone
Your your language, test version, state and representative, interview date, study progress, test history and settings are saved only in the app's storage on your device. Deleting the app deletes them. If you use Export data in Settings, the app creates a backup file and you choose where it goes (for example Files or a message to yourself); we never receive it.
Microphone and speech recognition
The mock interview can listen to your spoken answer, only after you allow microphone and speech recognition access and only while you are answering. Speech is turned into text on your device wherever the phone supports it. On some phones the operating system's speech service (Apple or Google) may process the audio under its own privacy policy. Oathway does not record, keep or send your audio or the recognised text to us. The app also reads questions aloud using your phone's built-in text-to-speech.
Notifications
If you turn on the daily reminder, the app schedules it on your phone. No push service or server is involved.
Content updates
The app may download updated question data from https://devca.app. Like any web server, it briefly logs the request (IP address, time, app version) for security and is not used to identify you.
Services that receive data
Oathway uses the following services. Each acts as our processor or as an independent controller under its own policy.
| Service | Data | Why |
|---|---|---|
| Google Firebase Analytics | How the app is used (screens opened, tests taken, settings chosen), an app instance ID, device model, OS version, language and approximate country | Understanding which features help and fixing what doesn't |
| Google Firebase Crashlytics | Crash reports: device model, OS version, app version and what the app was doing when it crashed | Finding and fixing bugs |
| Google Firebase Remote Config | An app instance ID | Adjusting settings (for example how often ads appear) without an app update |
| Google AdMob | Advertising ID (only where you allow it), IP address, approximate location derived from it, device and app information, ad interactions | Showing ads in the free version, measuring them and preventing fraud |
| RevenueCat | A random app user ID, purchase receipts and purchase history from Apple or Google | Unlocking the paid upgrade and restoring it on a new phone |
Ads, consent and tracking
- EEA, UK and Switzerland: the first time you open the app, a consent form from Google lets you choose whether your data can be used for personalised ads. You can change your choice any time in Settings → Privacy choices.
- iPhone: the app asks for permission to track (App Tracking Transparency). If you say no, your advertising ID is not shared and ads are not personalised. You can change this in iOS Settings → Privacy & Security → Tracking.
- Android: you can reset or delete your advertising ID in Settings → Privacy → Ads (or Google → Ads).
- US state privacy laws: showing personalised ads may count as "sharing" for cross-context behavioural advertising. You can opt out by declining personalised ads or tracking as described above. We do not sell personal information for money.
If you buy the paid upgrade, ads are turned off.
Legal bases (EEA/UK)
We rely on your consent for personalised ads and tracking; on our legitimate interest in keeping the app working, secure and improving for analytics, crash reports and non-personalised ads; and on performing our contract with you for purchases.
How long data is kept
Data on your phone stays until you delete it or the app. Data held by the services above is kept under their retention settings; we keep analytics data for no longer than 14 months.
Your rights
Depending on where you live, you may have the right to access, correct, delete or restrict the use of your personal data, to object to its use, to data portability and to withdraw consent. Because Oathway has no account, we usually can't link data to you; most choices are made in the app or your phone's settings as described above. You can also email us, and you may complain to your local data protection authority.
Children
Oathway is not directed at children under 13, and we do not knowingly collect personal information from them.
International transfers
The services above may process data outside your country, including in the United States, under safeguards such as the EU Standard Contractual Clauses.
Changes
If this policy changes, we will update the date at the top of this page and, for important changes, tell you in the app.
