Answers
- All answersPlain answers about private notes.
- Does Notion AI read my notes?Yes: when you use Notion AI, the content it works on is sent to large language models run by Notion’s AI providers, not processed on your device.
- Is Google Keep private?Google Keep notes are private from other people unless you share them, but not from Google: Google does not describe Keep as end-to-end encrypted, so it can access your notes.
- Are Apple Notes end-to-end encrypted?Only if you turn on Advanced Data Protection: by default, notes in iCloud are encrypted with keys Apple holds, so they are not end-to-end encrypted.
- Does Evernote sell my data?Evernote’s privacy policy says it is “not in the business of selling or renting your personal data.”
- Is Obsidian private?Yes: Obsidian stores your notes as files on your own device, says your data is never sent to its servers, and collects no telemetry.
- Is there a notes app that doesn’t train on my data?Yes — several popular notes apps state that they do not use your notes to train AI models, including Notion, Evernote and Apple Notes.
- What is zero-knowledge encryption?Zero-knowledge encryption means your data is encrypted with a key the service does not have, so the company storing it holds nothing it can read.
- What is end-to-end encryption?End-to-end encryption means data is encrypted on your device and can only be decrypted on another device you (or the person you are sending it to) control.
- Can a notes app read my notes?Most cloud notes apps can, because they encrypt your notes with keys they hold.
- Is there an offline notes app with on-device AI?Yes, a few exist, though most notes apps with AI features send your notes to a cloud model.
- What happens to my notes if the company shuts down?If your notes live on the company’s servers, you have until the service shuts down to export them, and then they are gone.
- Do I need a cloud notes app?You need a cloud notes app if you want the same notes on several devices without moving them yourself, or want to share and edit notes with other people.
- Is on-device AI as good as cloud AI?Not for everything: the models that fit on a phone or laptop are far smaller than the ones cloud services run, so they are worse at long writing and complex reasoning.
- How does encrypted sync work?Encrypted sync encrypts each note on your device before it is uploaded, so the sync server only ever stores scrambled data it has no key for.
- Why is there no “forgot password” button?Because a “forgot password”
