Terms of Use
Effective 9 November 2026.
These Terms are the agreement between you and Shahla Babayeva ("we", "us") for the PolyLing: AI Language Partner app ("the app"). By using the app you accept them. If you don't agree, please don't use the app. Our Privacy Policy explains how we handle your data.
1. Who can use PolyLing
You must be at least 13 years old. If you are under the age of majority where you live, a parent or guardian must agree to these Terms for you.
2. Your partners are AI
Every conversation partner is an artificial intelligence, not a real person. Partners can make mistakes, including in grammar, translations, corrections, facts and level estimates. PolyLing is a practice tool: it is not a certified language course or exam, and nothing a partner says is professional, medical, legal or financial advice. Partners are friendly practice partners only; romantic or sexual role-play is not offered.
3. Acceptable use
Please don't:
- use the app for anything illegal, or to create sexual content involving minors, threats, harassment or hate;
- try to make partners produce harmful content, reveal their instructions, or behave outside their role;
- get around limits, use automated tools or scripts, resell access, or copy, reverse-engineer or overload the service;
- share sensitive personal details about yourself or others in conversations.
Messages are checked automatically for safety. We may limit, suspend or end access if these rules are broken.
4. Free use
Without a subscription you get one free text conversation (up to 20 of your messages) and its report. Features and limits of the free version may change.
5. Subscriptions
- Plans: PolyLing Pro is offered weekly, monthly or yearly. Prices are shown in the app before you buy, in your local currency.
- Free trial: the yearly plan may include a free trial (currently 3 days) for eligible new subscribers. If you don't cancel at least 24 hours before the trial ends, the yearly subscription starts and you are charged. Weekly and monthly plans have no free trial.
- Payment and renewal: payment is charged to your Apple ID at confirmation of purchase (or at the end of the trial). Subscriptions renew automatically at the same price and length unless cancelled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends.
- Managing and cancelling: manage or cancel in your Apple ID settings (Settings → your name → Subscriptions), or from Settings → Manage subscription in the app. Cancelling stops the next renewal; you keep Pro until the end of the period you paid for. Deleting the app or your data does not cancel a subscription.
- Refunds: purchases are handled by Apple and refunds follow Apple's policies. Request one at reportaproblem.apple.com.
- Price changes: Apple will tell you in advance and, where the law requires, ask for your consent.
6. Voice minutes and fair use
- Each plan includes a voice-minute allowance: weekly 40 minutes per week, monthly 200 minutes per month, yearly 150 minutes per month. The app always shows what is left and when it resets. Unused minutes don't carry over.
- Extra minute packs are one-time purchases (consumables). Their minutes can be used until the end of your current allowance period and are not refundable once used.
- Text conversations have a fair-use limit of 300 messages per day.
- To keep the service available for everyone, we may pause AI features briefly during unusually high demand.
7. Your content
You own what you write and say. You give us permission to process it only to run the app (for example to send it to our AI provider to write replies). Conversation history is stored on your phone; see the Privacy Policy for details.
8. Our content
The app, its partners, characters, texts, voices, design and name belong to us or our licensors. We give you a personal, non-transferable, non-exclusive licence to use the app on Apple devices you own or control, as allowed by the App Store Terms of Service.
9. Changes and availability
We may update the app, add or remove features or partners, and change these Terms. If a change is significant, we will tell you in the app before it applies. We can't promise the app will always be available or error-free.
10. Ending
You can stop using PolyLing at any time and delete your data in Settings → Delete all my data. We may end your access if you seriously or repeatedly break these Terms.
11. Disclaimers and liability
The app is provided "as is" and "as available". To the extent the law allows, we disclaim implied warranties, and we are not liable for indirect or consequential losses, or for losses caused by relying on AI output. Our total liability to you is limited to the amount you paid for the app in the 12 months before the claim. Nothing in these Terms limits rights you have as a consumer under the laws of your country that cannot be waived.
12. Apple
These Terms are between you and us, not Apple. Apple is not responsible for the app or its content. Apple has no obligation to provide maintenance or support for the app. If the app fails to meet an applicable warranty, you may notify Apple and Apple will refund the purchase price, if any; Apple has no other warranty obligation. Apple is not responsible for any claims relating to the app (including product liability, failure to meet legal requirements, consumer protection, privacy or intellectual property claims); we are, to the extent these Terms don't exclude it. You confirm you are not in a country under a U.S. Government embargo or designated as "terrorist supporting", and that you are not on any U.S. Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. Where these Terms don't cover something, Apple's Standard End User Licence Agreement applies.
