commissure is built local-first on purpose: your personal data stays on your device. This explains the little that does leave it, and why.
The corpus commissure builds from your messages, email, browser history, notes, files, and other sources lives on your own device. We never upload it wholesale, and we cannot see it.
Using commissure.ai (accounts, the website, metered "ask") involves our cloud, which handles only:
If you connect Gmail or Google Calendar, commissure uses Google OAuth in the local Mac app to request read-only access. The OAuth tokens are saved on your device, and Gmail messages plus Calendar events are ingested into your local corpus so you can search, summarize, and reason over your own context.
Google data is not uploaded wholesale to commissure.ai. It leaves your device only when you explicitly use a cloud AI feature that sends the question and the selected snippets needed to answer it. We do not sell Google user data, use it for advertising, or use it to train models.
commissure's use and transfer of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements.
Only the providers needed to operate: Anthropic / OpenAI / Google (model inference on the request you submit, for the model route you picked), Stripe (payments), Cloudflare (hosting), Resend (sign-in and invite emails), and Twilio (invite texts, when you ask us to send one). We do not sell your data, ever, and it is not used to train models.
The website uses only the essential cookies needed to keep you signed in. No advertising or third-party tracking cookies.
Our cloud runs on Cloudflare and may be processed in the United States and other countries where our providers operate. The model provider you choose processes your request in its own regions.
You can access, correct, export, or delete your account data, and object to or restrict how it is used. Where the law grants these rights (including the EU's GDPR and California's CCPA/CPRA), we honor them for everyone. We do not sell or "share" your data for advertising. To exercise any right, email nik@commissure.ai.
Your local data is yours to delete on your device anytime. We keep your cloud account data until you delete it or close your account; email nik@commissure.ai and we'll remove it, and backup copies age out shortly after.
commissure is not for anyone under 18, and we do not knowingly collect data from them.
Accounts use passkeys (no passwords to leak), and cloud data is limited to the metadata above. No system is perfectly secure, but the local-first design means the sensitive part, your corpus, isn't ours to lose. The full practices (encryption, signing, what each subsystem can and cannot read) are on the Security page.
We may update this policy; material changes are posted here with a new date. Questions or requests: nik@commissure.ai.
