Your text

The free style check on this website runs entirely in your browser; that text never reaches our servers.

Text you send to the API (/v1/rewrite, /v1/check), including through the MCP server, CLI or integrations, is processed in memory to produce the response and then discarded. We do not store it, log it or use it to train models.

Rewrites are generated by Claude models running on Amazon Bedrock in the AWS European Union (Ireland) region. Amazon Bedrock processes the text to generate the response and, under AWS's terms, does not use it to train models.

Account data

• Your email address, plan and account status.
• A one-way hash of your API key (we cannot see or recover the key itself).
• Usage counters: words and requests per month.
• If you subscribe, your Stripe customer and subscription IDs.

We use this to run your account, enforce plan limits and bill you. It is stored on Amazon Web Services in the European Union. Request logs contain only metadata (a shortened account ID, word counts, timings) and are deleted after 30 days.

Payments

Payments are handled by Stripe. Card details go directly to Stripe and never reach our servers. See Stripe's privacy policy.

Waitlist

If you joined the waitlist, we keep your email and the time you joined, only to contact you about Sounday.

Your browser

This site sets no cookies and uses no third-party trackers. If you create or enter an API key here, it is saved in your browser's local storage so the account page remembers it. “Forget key on this device” removes it.

Your rights

You can ask for a copy of your data, a correction or deletion of your account at any time by writing to support@sounday.ai. We answer within 30 days. Processors we use: Amazon Web Services (hosting, Bedrock), Stripe (payments).
