Terms of Service & End-User License Agreement (EULA)
Last updated: October 13, 2026
📌 Key Points at a Glance (TL;DR)
- Your Content is Yours: You retain full ownership of all text and audio you translate. LinQo does not use your private messages to train public AI models.
- Subscriptions Auto-Renew: Apple App Store and Stripe subscriptions renew automatically unless cancelled at least 24 hours before the current period ends.
- App Deletion Does Not Cancel Subscriptions: Simply deleting the LinQo app or your account does not cancel your App Store subscription. You must cancel in your Apple ID settings.
- AI Nature: LinQo uses neural machine translation and large language models. While highly accurate, do not rely on it for critical legal, medical, or life-safety decisions.
1. Acceptance of Terms & License Agreement
These Terms of Service and End-User License Agreement ("Terms" or "EULA") constitute a legally binding agreement between you ("User," "you") and LinQo ("LinQo," "we," "us," or "our"). By downloading, installing, accessing, or using the LinQo keyboard application ("App"), web dashboard, or related APIs ("Service"), you agree to be bound by these Terms.
If you do not agree to these Terms, you must not download, install, access, or use the Service, and you must immediately uninstall the App from all your devices.
2. Description of Service & Product Scope
LinQo provides an AI-powered input keyboard extension for iOS and Android, companion mobile applications, and a web management dashboard. The Service processes and translates text entered by users in real time across 60+ supported languages, offering tone adaptations (e.g., formal, friendly, business), context-aware rephrasing, grammatical refinement, and personal vocabulary glossaries using cloud-based and on-device neural processing technologies.
3. User Accounts, Device Limits & Security
- Account Registration: Certain features require an account created via email, Apple Sign-In, or Google Sign-In. You agree to provide accurate, current, and complete information.
- Credential Security: You are solely responsible for maintaining the confidentiality of your credentials and for all activities that occur under your account.
- Device Allocation: Each account is subject to active device limits based on your tier (Free: 1 device; Standard: up to 3 devices; Pro: up to 5 devices). LinQo reserves the right to unbind inactive devices exceeding plan thresholds.
- Single User Policy: Accounts are non-transferable and intended for personal use by the registered individual, except where explicit multi-seat or family entitlements are provided.
4. Subscription Plans, Pricing & Fair Use
LinQo offers both free and auto-renewable subscription tiers:
- Free Plan: Includes 5 messages per day, 1 active device, 60+ languages, and standard AI-powered translation. Free Plan keyboard output includes a discrete promotional product attribution signature ("✨ via LinQo Keyboard"). Users maintain full control to manually edit or delete this attribution before sending messages. The attribution signature is automatically removed upon upgrading to any paid plan or during active trial periods.
- Standard Plan: €3.99/month or €38.28/year (or US storefront equivalent $3.99/month, $39.99/year — $3.33/month). Includes 100 messages per day, up to 3 active devices, 50 custom glossary terms, clean messages without watermark attribution (100% privacy), all tone and rephrasing styles, gender-aware grammar, and priority customer support.
- Pro Plan: €7.99/month or €76.68/year (or US storefront equivalent $7.99/month, $76.90/year — $6.41/month). Includes 500 messages per day, up to 5 active devices, 500 custom glossary terms, all Standard features (including 100% clean messages), AI Advisor, and priority API processing.
Fair Use & Message Definition
For the purposes of plan limits, a "message" is defined as a translation or AI rephrasing request containing up to 1,000 characters. Requests exceeding 1,000 characters are calculated in 1,000-character increments. Daily message quotas reset automatically every 24 hours at 00:00 UTC. Unused daily messages do not roll over to subsequent days.
5. Mobile App Store Subscriptions (Apple App Store & Google Play Disclosures)

- Renewal Charges: Your Apple ID account will be charged for renewal within the 24-hour window prior to the end of the current period at the then-current subscription rate.
