Privacy Policy

Last updated: 8 November 2026

Audio

The lecturer's voice is turned into text by Apple's on-device speech recognition on your Mac. LecMind never records or uploads audio.

What text is sent

Recognised sentences, and the text of course files you upload, are passed through LecMind's server to Anthropic's Claude models for translation, term explanations, summaries and assessment guides. LecMind's server only passes them on and does not store them. Under Anthropic's commercial terms, this content is not used to train models by default.

What LecMind's server keeps

A randomly generated device ID (not your Mac's serial number), your time zone (to count class time by month), how many minutes you used each month, your subscription's transaction ID and expiry date, and your email if you choose to give it. We do not keep your name, course content, captions or summaries. Service logs are kept for 30 days.

Apple device check

So that each Mac can claim the free week only once, LecMind uses Apple's DeviceCheck to set a "free week used" flag for your Mac. Apple keeps this flag, and it stays even if you delete the app or your data. It only says that this Mac has used its free week; it contains no personal information and we can't identify you from it.

Payment

Apple takes payment for the monthly and yearly plans. LecMind never sees your payment details.

Stored on your Mac

Captions, summaries, course files, glossaries and profile details such as your nickname, university and major are stored only on your Mac.

Email

Email is optional. If you give it, it is kept on LecMind's server and used only for important notices (such as subscription and service changes). You get news and offers only if you tick "email me". Change or delete it any time in the app's Settings.

Deletion

Settings › Data & Privacy › Delete all data in the app also deletes your Mac's records and your email on LecMind's server. Your subscription itself is managed in your Apple Account.

Third parties

Anthropic (AI models), Cloudflare (server) and Apple (App Store, payment and device check). We do not sell your data or use it for advertising.

Children

LecMind is made for university students and is not directed at children under 13.
