Koevo Terms of Use

1. The service

Koevo, made by RankAiro Ltd trading as Syntax Planet, converts text into speech using AI voices and lets you create a copy of your own voice. By using the app you agree to these terms. If you do not agree, do not use the app.

2. Credits and plans

Generating speech uses credits: about 1 credit per 10 English letters or 3 Japanese/Korean characters, rounded up per clip. New devices receive a free starting balance, a daily top-up, and credits for watching optional rewarded ads. Credit packs can be bought once through Apple. Koevo Pro is an auto-renewing weekly or monthly subscription bought through Apple that adds a credit allowance each period, removes ads and raises the per-clip text limit.

Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and are managed in your Apple ID settings. Used credits are not refundable. Refund requests for purchases are handled by Apple.

3. Your voice and your content

You may only clone a voice that is your own. Before recording you confirm that the voice is yours and that you will not clone anyone else. You keep ownership of your recordings and of the audio you generate; you grant us the right to process them to provide the service.

You are responsible for the text you convert and for how you use the audio. Do not use Koevo to deceive, harass, defame or impersonate anyone, to infringe rights, or to produce content that is illegal where you are.

4. Voice library

Licensed voices are provided under licence from their owners. Community voices are uploaded by other users of our speech provider and may resemble real people; they are offered as-is and you are solely responsible for any use of them. Do not use any voice to make it appear that a real person said something they did not. If you believe a voice violates your rights, contact us and we will remove it from the app.

5. Acceptable use

Do not attempt to bypass credits, attestation or rate limits, reverse-engineer the service, or use it to build a competing voice model. We may restrict or terminate access for misuse.

6. Availability and changes

The service depends on third-party providers and may be unavailable at times. We may change features, prices and these terms; material changes will be shown in the app. Continued use after a change means you accept it.

7. Disclaimer and liability

The app is provided "as is" without warranties of any kind. To the fullest extent permitted by law, we are not liable for indirect or consequential damages, and our total liability for any claim is limited to the amount you paid us in the 12 months before the claim.

8. Apple

These terms are between you and us, not Apple. Apple's standard Licensed Application End User License Agreement also applies to your use of the app.
