Privacy policy
Last updated 11 November 2026
This policy explains what Sylphe collects, why, and the choices you have. In short: your profile, CV and History stay encrypted on your Mac; our servers keep your account, your plan and how much you used, and nothing else about your interviews.
What we collect
Account: your name, email and how you sign in (email, Google or GitHub). Billing: your plan, its status and renewal date. Payments are handled by Lemon Squeezy; we never see your card. Usage: minutes listened, answers, screen reads and token counts, with dates, so limits and bills are right. What you send for an answer: short pieces of call audio, the question text, and only the facts from your profile that the question needs. Error reports from the app: what failed, where, the app version and your system version. They never include call audio, transcripts, answers, files or screenshots, and you can turn them off in the app’s Settings.
What stays on your Mac
Your profile, CV, portfolio, facts, transcripts and History are stored on your Mac, encrypted with a key in your Keychain. We cannot read them.
How we use it
To give you answers, keep within your plan, bill you, keep the service secure, and answer support requests. We do not sell your data, show you ads, or use your content to train AI models.
Who processes it for us
Anthropic (writes answers), Deepgram (turns speech into text), Lemon Squeezy (payments, as merchant of record), Google Firebase (accounts and database) and Netlify (hosting). Each processes data only to provide its part of the service.
How long we keep it
Account details: until you delete your account. Usage records: up to 24 months, for billing and tax. Error reports: up to 12 months. Audio and question text sent for an answer: not stored by us after the answer is written.
Your rights
You can see, export or delete your data from your account at any time, or by emailing us. If you are in the EU or UK you also have the right to correct it, object, and complain to your data protection authority.
Security
Traffic is encrypted (TLS). Our database is encrypted at rest. API keys live only on our servers, never in the app on your Mac.
Children
Sylphe is not for anyone under 16.
Changes and contact
We will tell you by email before any change that affects you. Questions: privacy@sylphe.app.
