LingoShift — Terms of Use & Privacy Policy

Last Updated: September 2026

1. About LingoShift

LingoShift is an AI translation app for iOS and Android, developed independently by Zahid Khalilov. It translates text using Google's Gemini AI, with an optional on-device offline mode for select languages.

2. Acceptance & Eligibility

By using LingoShift, you agree to these terms. You must be at least 13 years old; if you're under 18, a parent or guardian must have agreed to these terms on your behalf.

3. How It Works

• Online: your text is sent to Google's Gemini AI (via Firebase) to produce a translation.
• Offline (Premium): select languages translate entirely on your device via Google ML Kit — nothing leaves your device.
• No account required to translate: an anonymous device ID keeps your settings and usage. Signing in with Google is optional, only needed to buy Premium or credit top-ups.

4. Privacy & Data

• Your translations are never stored on our servers — not the text you type, not the result you get, not even temporarily. It's processed by Gemini AI purely to produce your translation, and it's yours — we claim no ownership over it.
• No login is required to use the app. If you choose to sign in with Google to purchase, we store your Google email and account ID — see "Optional Google Sign-In" below. We never collect your phone number or contacts.
• Recent translations and bookmarks live only on your device (until you delete them), never synced to the cloud.
• We store minimal metadata (device info, translation counts, premium/credits status) to run the app and enforce free-tier limits.
• No ads, no analytics/tracking SDKs, and we don't sell your data.
• Google (Firebase, Gemini AI) and RevenueCat process data on our behalf — see their Google Privacy Policy and RevenueCat Privacy Policy.

5. Optional Google Sign-In

Signing in with Google is optional — translating and your free credits never require it. It's only needed to buy LingoShift Pro or credit top-ups, so your purchase is tied to your account and follows you if you reinstall the app or switch devices. Signing in stores your Google account email and ID; we don't post anything, read your contacts, or access anything beyond your basic profile. You can sign out anytime from Settings.

6. Purchases & Subscriptions

• Free tier: a rolling AI-translation credit allowance that refills every 8 hours.
• Credit top-ups: a one-time purchase for extra credits.
• LingoShift Pro: a Monthly or Yearly subscription removing the credit limit, raising the text-length cap, and unlocking Offline translation.
• Billing, refunds, and cancellation are handled entirely by the App Store or Google Play under their own terms — we never see your payment details. Manage or cancel anytime from your device's store account or LingoShift's Settings.

7. Data Deletion & Permissions

There's no required account to delete — uninstalling removes everything stored on your device. If you signed in with Google, you can unlink it anytime from Settings. To delete your usage record or Google-linked purchase history from our servers, email us below. LingoShift only requests internet access (translation, purchases) and storage access (downloading offline language packs) — never your camera, contacts, or location.

8. Disclaimers & Liability

LingoShift is provided "as is." AI translations can be inaccurate — don't rely on them for legal, medical, or other critical decisions. We aren't responsible for the third-party services this app relies on (Google, RevenueCat), and to the extent permitted by law, we're not liable for damages arising from your use of the app.

9. Changes to These Terms

We may update these terms from time to time; continued use of the app after a change means you accept the revision. These terms are governed by applicable law.
