Choose Proton Mail if:
People and teams for whom mail confidentiality is a requirement rather than a preference.
Logseq: pros & cons
- Your notes stay as local Markdown files
- Open source, no vendor to depend on
- Linked references and graph view
- Outliner structure does not suit everyone
- Sync requires setup or a paid add-on
- Performance drops on very large graphs
Proton Mail: pros & cons
- End-to-end encryption by default between Proton users
- Swiss jurisdiction and a clear privacy stance
- Free tier available
- Encryption breaks the usual IMAP workflow
- Search inside encrypted mail is limited
- Costs more than mainstream mail providers
Our verdict on Logseq
The strongest option if file ownership matters. Expect to solve sync yourself.
Our verdict on Proton Mail
Buy it for the threat model, not the features. If privacy is not your reason, a mainstream provider is more convenient.
