Support
We answer support email ourselves — there is no ticket maze.
Email us
Write in English, Chinese or Japanese. We reply within [TODO — to be confirmed: the support response time we commit to, e.g. 2 business days] Please include your device and OS version, the app version, and — if a job failed — roughly when it happened, so we can find it in the logs. Never send passwords or API keys.
What we can help with
- A scan, conversion, recognition or generation job that failed or looks wrong
- Purchases, subscriptions, credits and refunds
- Access, export or deletion of your data, and account deletion (see the Privacy Policy)
- Open API and MCP access, keys and limits
- Reporting a security issue — please email us before disclosing it publicly
In the app
You can also reach support from inside the app: open Me and then the contact option. That attaches your app version and device details automatically, which makes a fault easier to trace.
Availability of the apps
The global Android and iPhone builds are still in preparation, so there is nothing to download from this site yet. The availability section on the home page is updated as each route opens.
