No. Your text is sent only when you ask for a check. It is checked in memory and dropped as soon as the fix comes back. We count how many checks you make, never what they said, and your text is never used to train AI.

No. GrammarDeck fixes mistakes and leaves the rest alone. It keeps your meaning, your tone, your line breaks and your emoji. Every change is shown before it is applied, so you stay in control.

English for now. Support for more languages is planned.

One check or one tone rewrite of up to 50 words costs 1 credit. Longer text costs 1 credit for every 50 words it starts, so 120 words cost 3. The app shows the cost before it checks long text.

Pro includes 5,000 credits a month, counted from the day you subscribed, yearly plans too. If you use them all, add a pack of 1,000 credits from your account page. Pack credits are used after your included ones and expire at your next monthly reset. The daily limit of 1,000 credits still applies.

Checks pause until the limit resets: the daily one at midnight UTC, the monthly one on your reset day. Nothing else changes. Upgrade to Pro, or on Pro add credits, if you need more.

• Try the right-click menu or the shortcut instead.
