Privacy policy
Updated November 14, 2026.
In short: EnglishLock does not collect personal data. We do not ask for a name, email, phone number or account, there is no login, we do not use advertising, we do not sell or share data, and we do not track you. What you study and choose stays on your device. Below are the details, including what third parties (the stores, RevenueCat and the servers that deliver files) process on their own.
1. What stays only on your device
Learned words, progress, day streak, goals, apps chosen to lock, usage times and settings. This is never sent to us. If you delete the app, or use "Delete my data" in Settings, all of it goes away.
2. What the app does not see
We do not see messages, photos, passwords, contacts, location or what you do inside other apps. The app only knows which app was chosen to lock and whether, at that moment, it is open.
3. Phone permissions and what they are for
iPhone
- Screen Time (Family Controls): lets you choose which apps to lock and stop them from opening. Apple shows the app picker to the system; EnglishLock does not receive the names or the content of the apps, and this data does not leave the device.
- Microphone and Speech Recognition (optional): used only when you answer by speaking. Recognition is done by the iPhone system, on the device itself whenever it allows. EnglishLock does not record or store the audio.
- Notifications (optional): local reminders that the app itself schedules on the device.
Android
- Usage access: lets the app know which application is open on the screen, only to lock the ones you chose. This information is processed on the device and is not sent or stored outside it.
- Display over other apps: lets the 5-word gate screen show on top of a locked app.
- Foreground service and ongoing notification: the app keeps a discreet notice while it watches the locked apps.
- Start when the phone turns on: so the lock comes back on its own after a restart.
- Notifications (optional): local reminders.
- EnglishLock does not use Android's accessibility service.
You can remove any permission at any time in your phone's settings. Without them, the lock stops working.
4. Third parties that process data on their own
- Apple (App Store) and Google (Google Play): handle purchase, billing and refunds. We do not receive your payment data. Their processing follows the privacy policies of Apple and Google.
- RevenueCat: to confirm whether your subscription is active, the app uses the RevenueCat service. It receives a random identifier (which is not your name or email) and the purchase information, and may process technical connection data, such as the IP address, under the RevenueCat privacy policy. EnglishLock does not send them your study data.
- File hosting: the word audio is downloaded from a server. As with any download, the server sees the device's IP address to deliver the file. We do not link that to you.
5. This website
The website does not use tracking cookies and has no analytics tools, forms or sign-up. If you pause the animations, that choice is kept only in your browser (local storage) and is not sent. The website is hosted on Vercel, which technically logs visits (such as the IP address) to operate and protect the service, under its own policy. The sample audio is downloaded only when you tap it.
6. We do not sell, we do not share, we do not advertise
We do not sell or share personal data, we do not run targeted advertising, we do not build profiles and we do not use data to train artificial intelligence systems.
7. Your rights (GDPR, LGPD, CCPA/CPRA and similar laws)
Because we do not collect personal data, we have no information about you to access, correct, port or delete. You control everything on the device. For data that third parties process (Apple, Google, RevenueCat), use their channels. If you have any question or request about privacy, write to englishlock.app@gmail.com; we reply by email as soon as possible. You can also complain to the data protection authority of your country.
8. Children
EnglishLock is not directed at children and does not collect data from anyone, including minors. Anyone who is a minor should use it with a parent or guardian.
9. Security
Because your study data stays on the device, its protection depends on your screen lock and your phone's settings. Avoid sharing the device while it is unlocked.
10. Transfers between countries
We do not transfer personal data, because we do not collect it. The third parties in item 4 may process data in other countries, under their policies.
11. Changes to this policy
If we change anything, we update this page and the date at the top. If the change is significant, we tell you in the app.
