Privacy Policy
Last updated: August 9, 2026 • Effective date: July 3, 2026
Short version. Aitra is an on-screen and face-to-face translation app. We do not require an account and we do not collect your name, email, phone number, or contacts. To translate, the specific text or speech you choose to translate is sent securely to our translation service (powered by Google's Gemini models) and returned to you. Image text is read on your device; we do not upload or store your screenshots. We use anonymous identifiers to enforce free usage limits and to verify subscriptions, to credit any Face‑to‑Face minutes you purchase, and (for non‑subscribers) to show ads.
This Privacy Policy explains how Aitra ("Aitra", "we", "us", or "our") handles information when you use the Aitra mobile application (the "App"). By using the App, you agree to the practices described here. If you do not agree, please do not use the App.
1. Who we are
Aitra is an independent application that provides AI‑powered translation of on‑screen text and live, face‑to‑face voice conversations. The App has no user accounts and no login. For any questions about this policy or your data, contact us at aitra@aitraapp.com.
2. Information we collect
2.1 Content you choose to translate
- Text you translate. When you use the floating translation bubble or the manual translation box, the text you point to or type is sent to our secure backend to be translated.
- On‑screen text captured for translation. When native on‑screen text is not available, the App may take a screenshot and read the text from it entirely on your device using Google ML Kit (on‑device text recognition). The screenshot itself is never uploaded or stored; only the recognized text is sent for translation.
- Voice/audio (Face to Face). If you use the "Face to Face" live translation feature, the audio captured from your microphone is streamed to our translation service to be translated in real time. Audio is used only to produce the translation and is not stored by us for other purposes.
The content you translate may contain personal or sensitive information depending on what is on your screen or what is spoken. Please only translate content you are comfortable sending to a translation service. Do not use Aitra to translate passwords, payment details, or other secrets.
2.2 Identifiers and technical data (collected automatically)
- Anonymous app / installation identifier. We use an anonymous identifier (such as the Android App Set ID and a RevenueCat anonymous ID) to count your free daily translations, to apply usage limits, and to verify whether you have an active Aitra Pro subscription. These identifiers are not linked to your real‑world identity.
- Advertising ID. For users on the free tier, Google AdMob may use the device's advertising identifier to serve ads (both optional rewarded ads and occasional full‑screen interstitial ads). See Section 6.
- App integrity signals. We use Google Play Integrity via Firebase App Check to confirm that requests come from a genuine, unmodified copy of the App, protecting our service from abuse.
- Usage and diagnostic data. We process minimal technical data required to operate the service, such as translation counts, timestamps, language codes, coarse device/OS information provided by the platform, and error logs.
2.3 Purchases
Purchases are processed by Google Play Billing and managed with RevenueCat. We do not receive or store your credit/debit card number or full payment details. There are two kinds of purchase:
- Aitra Pro subscription. We receive a purchase/subscription status token used to unlock Pro features.
- Face‑to‑Face minute packs (one‑time purchases). When you buy a minute pack, RevenueCat notifies our backend, which adds the purchased minutes to a balance stored against your anonymous identifier. We receive the product identifier and a transaction identifier — not your payment details. The balance is credited on our server (not on your device) so that it cannot be created without a real purchase.
2.4 What we do NOT collect
- No name, email address, phone number, or postal address.
- No contacts, photos library, precise GPS location, or call/SMS logs.
- No screenshots or recordings are uploaded or stored on our servers.
- No user account or password (the App has no sign‑in).
3. How the Accessibility Service is used
Important
Aitra uses Android's Accessibility Service for one purpose only: to read the text on your current screen at the point you choose, so it can be translated instantly inside any app. The Accessibility Service is not used to collect, log, sell, or share your personal data, and it is not used for advertising or analytics. Text read this way is used solely to perform the translation you requested. You can turn the Accessibility Service on or off at any time in your device's Settings → Accessibility.
4. How we use information
- To provide the core service: translate the text and speech you request.
- To enforce free‑tier limits and grant bonus translations for watching rewarded ads.
- To verify Aitra Pro subscription status and unlock Pro features.
- To credit and track the Face‑to‑Face minute balance you have purchased.
- To protect the service from fraud, abuse, and excessive cost (App Check, rate/budget limits).
- To show ads to non‑subscribers and, where required, request your consent for them.
- To diagnose problems, maintain reliability, and improve performance.
We do not sell your personal information, and we do not use the content you translate to build advertising profiles about you.
5. Third‑party services (sub‑processors)
To operate Aitra we rely on the following providers, which process data on our behalf or as independent controllers under their own privacy policies:
| Provider | Purpose | Data involved |
|---|---|---|
| Google Gemini API (Google LLC / Google Cloud) | Performs the AI translation of text and speech | The text/audio you choose to translate |
| Google Firebase (Cloud Functions, Firestore, App Check) | Backend proxy, usage counters, translation cache, app‑integrity checks | Translation content (in transit), anonymous IDs, usage counts |
| Google ML Kit (on‑device) | On‑device text recognition (OCR) | Runs on your device; no upload |
| Google AdMob & User Messaging Platform (UMP) | Rewarded and interstitial ads for free users; consent management | Advertising ID, ad interaction data, consent choices |
| Google Play Billing | Processes subscription payments | Purchase tokens (no card details shared with us) |
| RevenueCat, Inc. | Subscription and one‑time purchase management; notifies our backend so purchased minutes can be credited | Anonymous subscriber ID, purchase status, product and transaction identifiers |
| Google Play Services / Play Integrity | App integrity and platform services | Device integrity signals |
Relevant policies: Google Privacy Policy (policies.google.com/privacy), RevenueCat Privacy Policy (revenuecat.com/privacy), and how Google uses data from apps that use its services (policies.google.com/technologies/partner-sites).
6. Advertising and consent
Free‑tier users may see two kinds of ad, both served by Google AdMob:
- Rewarded ads — entirely optional. You choose to watch one to earn additional translations when your daily free allowance runs out.
- Interstitial ads — a full‑screen ad that may appear when you turn on the floating translation bar. These are limited: never on your first use of the bar, and at most once per day.
If you subscribe to Aitra Pro, all ads are removed. In the European Economic Area, the United Kingdom, and other regions where required, we present a Google‑certified consent form (User Messaging Platform) before ads that use personal data are shown, and we respect your choice. You can reset ad personalization at any time through your device's settings and Google's ad settings (adssettings.google.com).
7. Data sharing and disclosure
We share data only as described in this policy: with the sub‑processors in Section 5 to provide the service, and when required by law, legal process, or to protect the rights, safety, and security of our users or the service. We do not sell your personal information.
8. Data retention
- Translations you request are processed to return a result. To improve speed and reduce cost, a translated snippet may be temporarily cached on our servers, keyed by a one‑way hash of the input; cached entries are shared for efficiency and are not associated with your identity.
- Usage counters (daily/monthly counts) are retained to enforce limits and are periodically reset.
- Purchased minute balances are retained against your anonymous identifier until you use them or ask us to delete them (see Data Deletion).
- Screenshots and audio are not retained by us (screenshots are processed on device; audio is streamed for real‑time translation and not stored for other purposes).
- We keep data only as long as necessary for the purposes above or as required by law.
9. Data security
Data in transit is protected with industry‑standard encryption (HTTPS/TLS). Our backend keeps AI provider keys server‑side (never in the App), verifies app integrity, and applies rate and budget limits. No method of transmission or storage is 100% secure, but we work to protect your information.
10. International data transfers
Our backend is hosted in the European Union (Frankfurt, Germany). Some sub‑processors (e.g., Google and RevenueCat) may process data in the United States or other countries. Where required, such transfers rely on appropriate safeguards (such as the EU Standard Contractual Clauses).
11. Your rights
Depending on where you live (for example, under the EU/UK GDPR or the California CCPA/CPRA), you may have rights to access, correct, delete, or restrict processing of your personal data, to object to processing, to data portability, and to withdraw consent. Because Aitra has no account system and uses only anonymous identifiers, we typically hold little or no data that identifies you. To make a request or ask a question, email us at aitra@aitraapp.com. You also have the right to lodge a complaint with your local data protection authority.
You can control the App's data flows directly on your device: disable the Accessibility Service, revoke the microphone or overlay permissions, reset your advertising ID, or uninstall the App.
12. Children's privacy
Aitra is not directed to children and is intended for users aged 13 and older (or the minimum age required in your country). We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will take appropriate action.
13. Permissions we request
| Permission | Why |
|---|---|
| Display over other apps | To show the floating translation bubble and result card over other apps. |
| Accessibility Service | To read the on‑screen text you choose so it can be translated (see Section 3). |
| Microphone (record audio) | Only for the "Face to Face" live voice translation feature. |
| Notifications | To show the required foreground‑service notification while translation is active. |
| Internet / network state | To send translation requests and check connectivity. |
| Advertising ID | Used by Google AdMob to serve rewarded and interstitial ads to free users. |
14. Changes to this policy
We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above and, where appropriate, provide additional notice. Your continued use of the App after changes take effect means you accept the updated policy.
