FAQ

Frequently asked questions

What languages does Rimo support?+
Rimo supports 25+ languages including Japanese, English, Spanish, French, German, Chinese (Simplified & Traditional), Korean, Portuguese, Russian, and more.
How are characters counted?+
The full text of the source message counts toward your monthly quota. Only the message being translated is counted — the translated output does not count.
Do I need to set up OAuth to use Rimo?+
No. Thread mode works immediately with no additional setup. OAuth is only needed if you want translations to appear inline in the original message.
What happens when I reach my monthly limit?+
Translations pause until the quota resets on the 1st of each month. You'll receive a warning at 80% usage and an upgrade prompt when you hit 100%.
Is my message content stored?+
No. Rimo stores only metadata (character counts, timestamps) for billing — not the content of your messages. Messages are sent to our AI provider for translation and are not retained.
