Privacy Policy

Data collection

We collect four types of information from our users: email, end-to-end encrypted data, metadata, and usage data. Your email is used for identification and communication purposes. End-to-end encrypted data refers to the data you store in DeepNotes, such as notes and arrows. Metadata refers to information about your data, such as creation date. Usage data helps us measure and improve the app.

Data protection

DeepNotes uses end-to-end encryption to protect your information. Only you have the key to your information, making it inaccessible to anyone else, including DeepNotes.

Your email is the only piece of information, along with metadata, that is not end-to-end encrypted. This is because we need to know your email in order to identify and communicate with you. In order to keep your email as protected as possible, we keep your email pepper-encrypted in our database.

For more details on how we protect your data, please refer to our security whitepaper.

Data storage

DeepNotes stores all of its data in the United States. While already being end-to-end encrypted, the data is also encrypted at rest.

Data processing

DeepNotes shares your email with Stripe for payment processing. We also process usage data in order to helps us understand how people use DeepNotes and how to make the app better. Usage data is anonymous and can't be linked back to you.


We use Stripe for payment processing. Stripe introduces some cookies in order to fulfill their task. Apart from those cookies, DeepNotes only uses cookies for user authentication and session management.
