Audio stays on your device
Recordings are stored on the device that made them and are not uploaded to our servers.
Class Notes privacy notice
This notice covers Class Notes for Mac, iPhone and iPad. It is separate from the Linelark privacy notice, because Class Notes works differently: it has an account, it syncs between your devices, and it sends audio and text to AI services to do its job.
Text syncs through your account
Transcripts, summaries and AI conversations are stored in your account so they appear on all your devices.
AI services process what you send
Audio sent for transcription and text sent for analysis are processed by the AI providers listed below.
No ads, no analytics SDK
The app contains no advertising and no third-party analytics library.
Who is responsible
Class Notes is developed and operated by Calogero Cascio, an independent developer in Milan, Italy, who is the data controller for the processing described here. For anything about your data, write to privacy@linelark.com.
Your account
To sync between devices you sign in with an email address and password, or with Sign in with Apple. We store your name, your email address (or the relay address Apple gives us) and a user identifier. Authentication is handled by Google Firebase Authentication.
Recordings and audio
Audio you record or import is saved on the device you used. It is not uploaded to our storage, and it does not sync to your other devices. When you transcribe a recording with a cloud engine, its audio is sent to the transcription provider you chose, processed, and the text is returned to the app.
Transcripts, summaries and conversations
Transcripts, titles, summaries, analyses, flashcards, action items, the questions you ask and the answers you receive are stored in your account in Google Cloud Firestore, so they are available on every device you sign in to. Images you attach to a conversation are stored in Firebase Storage.
AI providers
To transcribe, summarise and answer, the app sends the relevant audio or text to AI providers: OpenAI and Groq for transcription, and OpenAI, Anthropic, Google (Gemini) and Groq for analysis and chat, depending on the feature and the model. Requests pass through AIProxy, a service that keeps our API keys out of the app. These providers process the content to return a result; under their API terms they do not use it to train their models. On iPhone and iPad, transcription can also run entirely on the device, in which case the audio is not sent anywhere.
Sharing and contacts
If you add a contact, we store the link between your account and theirs, identified by email address. A recording you share becomes visible to that contact, including its transcript and summary. You can stop sharing or remove a contact at any time.
Purchases
Minute packs are bought through Apple’s App Store. Apple handles the payment; we receive a transaction record for the product you bought, which we use to add the minutes to your balance. We never see your card details.
Notifications
If you allow notifications, a device token is stored through Firebase Cloud Messaging so the app can tell you, for example, that a shared recording has arrived.
What the app does not do
It shows no advertising, contains no third-party analytics SDK, and does not sell or rent your data. The iPhone app may display Apple’s tracking permission prompt; whichever answer you give, no app feature changes and no data is shared for advertising.
Legal bases
We process your account, recordings and generated text to provide the service you asked for (performance of a contract, GDPR Art. 6(1)(b)); purchase records to meet our accounting obligations (Art. 6(1)(c)); and limited technical data to keep the service secure (legitimate interests, Art. 6(1)(f)).
International transfers
Google, OpenAI, Anthropic, Groq and AIProxy may process data in the United States and other countries outside the European Economic Area. Those transfers rely on the providers’ Standard Contractual Clauses or the EU–US Data Privacy Framework, as applicable.
How long we keep it
Your data stays in your account until you delete it. Deleting a recording removes its transcript, summary and analyses from all your devices. Deleting your account — in Settings › Account on iPhone or iPad — removes your account and the content stored in it. Copies in provider logs, if any, are deleted under those providers’ own retention periods.
Your rights
You can ask to access, correct, export or delete your personal data, to restrict or object to its processing, and to withdraw any consent you gave. Write to privacy@linelark.com. You can also complain to the Italian data protection authority, the Garante per la protezione dei dati personali, or to the authority where you live.
Children
Class Notes is not directed at children under 14. If you believe a child has given us personal data, write to us and we will delete it.
Changes
If this notice changes, the new version is published on this page with a new effective date.
