Questions, problems or data requests: email hello@syntaxplanet.com and include your device model and iOS version. We usually reply within two working days.

Do I need an account?

No. Koevo has no sign-up. Your device is identified anonymously, and your clips stay on your phone.

How do credits work?

Each clip uses about 1 credit per 10 English letters (or 3 Japanese/Korean characters). You get free credits every day, can watch a short ad for more, buy a credit pack, or go Pro.

How do I cancel Koevo Pro?

Open iOS Settings → your name → Subscriptions → Koevo and cancel at least 24 hours before renewal. Apple handles all billing and refunds.

My purchase is missing.

Open Koevo → Settings → Restore purchases. If credits still do not appear, email us with the date of purchase.

How do I delete my data or my cloned voice?

Settings → Delete my data removes your voice models and samples, usage records and device record from our servers and clears clips on your device.
