Privacy policy

Last updated: November 10, 2026

This policy explains how the Déclic Android app ("the app") handles your data. In short: no account, no ads, no data sold. Text you ask to translate is sent to a translation service, and nothing else leaves your phone apart from the exchange-rate request and, if the app crashes, an anonymous technical report.

1. Accessibility service

The app uses Android's AccessibilityService API, which you turn on yourself in the settings. It uses it only to:

• know which app is in the foreground, so the bubble only shows in the apps you picked (Pinduoduo by default);
• draw the bubble and translations over the screen;
• take a screenshot, only when you tap "Zone" or "Full screen".

The app does not read your chats, log your keystrokes, collect passwords or act on your behalf in other apps. The screenshot stays in memory while the text is read and is then discarded: it is never saved or sent.

2. Text recognition (OCR)

Text in the screenshot is recognized on your phone by Google ML Kit (through Google Play services). The image never leaves the device.

3. Translation

For online translation, the recognized text (or the text you type in "Reply") is sent to Google Cloud Translation, which returns the translation. Only the text and chosen languages are sent, with the app's technical identifier; no personal identifier. Google processes this data under its Google Cloud terms and privacy policy.

If the online service is unavailable, or for downloaded languages, translation runs on the device with Google ML Kit and the text is not sent anywhere. Language models are downloaded from Google's servers.

Avoid translating sensitive information (full address, card numbers…) if you don't want it to go through Google.

4. Exchange rates

To convert prices at today's rate, the app queries open.er-api.com (ExchangeRate-API). The request only contains the source currency; no personal data. The rate is kept on the phone and refreshed at most every 12 hours. With a fixed rate, no request is made.

5. Data stored on the phone

Your settings (languages, chosen apps, currency, rate) and the latest exchange rate are stored locally. Translations shown in the panel are not kept after it closes. Text translated with "Reply" is placed on the clipboard so you can paste it. Uninstalling the app deletes everything.

6. Crash reports

If the app crashes, it sends a technical report to Firebase Crashlytics (Google): error stack trace, phone model and Android version, app version, anonymous Firebase installation ID and time of the crash. The report contains no translated text, no screenshot, no name or contact details. These reports are used only to fix bugs. Google processes them under Firebase's privacy terms.

7. What the app does not do

• no user account, no sign-up;
• no ads or ad trackers;
• no selling, renting or sharing of data for commercial purposes;
• no collection of location, contacts or photos.

Apart from crash reports, Google Play services, used for text recognition and language models, may collect technical diagnostic data under Google's rules.

8. Payments

If the app offers a purchase or subscription, payment is handled by Google Play. We never receive your payment details.

9. Children

The app is not directed at children under 13 and does not knowingly collect data about them.

10. Your rights and contact

We run no server and keep no data about you; the only data we receive is the anonymous crash reports described above. For any question, or to exercise your GDPR rights: [contact e-mail to be added].

This policy may change with the app; the date above shows the latest version.
