Privacy Policy

Last updated: July 24, 2026

This policy explains what Cinder processes when you use the app, what is stored on your Mac and in your account, and the controls available on each plan.

What stays on your machine

Cinder stores a local copy of transcript text, call metadata, and generated outputs in an encrypted database on your Mac. Its database key and authentication credentials are protected by the macOS Keychain. Raw call audio is processed in real time and is never saved to disk by Cinder.

Free plan

On Free, transcription runs locally on your Mac. Raw audio is neither uploaded nor saved. Transcript text is stored in your Cinder account, remains accessible for 30 days, and may be used to improve Cinder’s AI under the disclosure you accept when using Free.

Starter and Pro plans

On the Starter trial and paid Starter or Pro, live audio is streamed to a cloud transcription provider and is not saved as audio. During the default Starter trial, transcript text stays local-only. On a paid Starter or Pro subscription, transcript text is stored on your Mac and in your Cinder account by default. You can disable cloud transcript storage; transcript text is then removed from Cinder’s servers while account metadata and generated outputs such as summaries may remain.

Paid transcript access is unlimited for transcripts you retain. Automatic cleanup defaults to 180 days and can be changed to 90 days, 180 days, 1 year, 2 years, 5 years or Forever.

AI coaching and analysis

When you request coaching or analysis, relevant conversation context is sent to Cinder’s configured AI providers. Paid-plan data is not used to train AI models. Generated coaching and analysis are returned to the app and may be stored locally and in your account according to the feature you use and your cloud transcript setting.

AI learning and memory

Cinder can automatically learn account-specific contact facts, account intelligence, sanitized writing-style examples from calls and edited follow-ups, and numerical call-behaviour patterns. High-confidence facts may be used immediately; uncertain or contradictory facts wait for review. You can inspect source evidence, verify, edit, dismiss, or delete facts, resolve conflicts, and review or delete writing-style examples with their source-call links. Each learning category can be disabled to stop new collection and prompt use without deleting existing items, or reset to delete its automatic learning. In the separate AI-memory setting, 1 year is the default. Accounts without a stored retention confirmation are not pruned until the setting is confirmed. You can choose 90 days, 180 days, 1 year or 2 years. Selecting 5 years or Forever is available on Starter and Pro. Verified facts, manual notes, documents, scripts, calls, and summaries are not pruned by the AI-memory setting; their own retention and deletion controls still apply. Deleting a call removes its indexed context and call-derived learning while keeping manual notes and pins.

What we store in the cloud

Account information, billing status, call records, contacts, transcript text, and generated outputs may be stored in Cinder's cloud to provide account history, search, sharing, and AI features. Free cloud transcript storage is required. During the default Starter trial, transcript text stays local-only. On paid Starter and Pro subscriptions, cloud transcript storage is on by default and can be disabled in Preferences; disabling it removes cloud transcript text and keeps future transcript text local, but account metadata and generated outputs such as summaries may remain. If you share a transcript with teammates or through a share link, the people you share it with can access it.

Free-plan improvement use

Free-plan transcript text may be used for model training and prompt optimization under the disclosure presented in the app. Before eligible text enters that improvement process, identifying speaker names are removed and the data is associated with a pseudonymous identifier rather than your name, email address, or account ID. Paid-plan transcript text is not used for this purpose. Upgrading stops future paid-plan data from entering the improvement process. Withdrawing the Free-plan acknowledgement triggers a best-effort request to remove associated improvement data; it does not promise instantaneous deletion from every prior processing stage.

Third-party services

Cinder uses service providers for paid cloud transcription, AI coaching and analysis, authentication and data storage, payments, integration authorization, website hosting, error monitoring, and product analytics. Cinder sends information needed for those functions. Those providers process information under their own terms and privacy policies.

Cinder uses Sentry for error and performance monitoring in the app and on this website, including sampled session replay on the website. This website also uses Vercel Analytics to understand anonymous marketing-site activity. Sentry is configured not to send default personally identifiable information. Website analytics are separate from the optional account-level product analytics setting in the desktop app.

Notice and consent

Cinder does not join a call as a participant bot. You remain responsible for providing any notice and obtaining any consent required by the laws that apply to your calls.

Your rights

You can request account deletion from within the app, clear local data from Settings, and, on a paid Starter or Pro subscription, disable or purge cloud transcript storage. We do not sell your data. Contact us to ask about access, correction, deletion, or other rights available where you live.

For a shorter product guide to these controls, read Privacy and data. Security practices are described separately on the Security page.
