Privacy Policy
Last updated: September 2026
We do not have your notes
Section titled “We do not have your notes”Not “we do not look at them”. We do not have them.
N2O has no cloud. There is no N2O server holding your vault, no backup of it, no index of it, no cache of it. If you asked us today to show you one line of one of your pages, we could not do it.
The reason is the way the plugin is built. N2O runs inside Obsidian, on your computer. When it syncs, it talks straight to Notion’s API from your machine. Your content goes from your computer to your Notion workspace and back again, and it never travels through anything of ours on the way.
What we never see, and what we have
Section titled “What we never see, and what we have”| We never see | We have |
|---|---|
| Your notes, in Notion or in your vault | Your email address, so a licence has something to attach to and product email has somewhere to go |
| The names of your pages and files | Your licence key |
| Your database rows and properties | |
| Your images and attachments | |
| Your Notion token | |
| Your vault, its folders, or how big it is |
That is the entire list on both sides. There is no third column.
You do not have to take our word for it
Section titled “You do not have to take our word for it”Open your network tools while a sync runs. Every request goes to api.notion.com. Your notes are markdown files in your own vault folder: open them in any text editor, with N2O uninstalled, with your internet off.
And if you never activate a licence, our server does not hear from you at all. Paste your own Notion integration token and N2O works without ever contacting us.
If N2O disappeared tomorrow
Section titled “If N2O disappeared tomorrow”Your notes would still be there. They are plain markdown files on your own disk, and they were never anywhere else. Nothing to export, nothing to rescue, no account to close before you lose access to your own writing.
That is the point of the product. Your notes stay yours, including from us.
We do not sell data. Ever.
Section titled “We do not sell data. Ever.”Not to advertisers, not to analytics companies, not to anybody, under any circumstances. We do not build a profile of you. There is no business here that is not you paying for the plugin, and we would like to keep it that way.
What N2O reads in Notion
Section titled “What N2O reads in Notion”Only the pages and databases you explicitly share with it, through your own integration or on the Notion approval screen:
- Page content: blocks, text, media
- Database properties and entries
- Page metadata: titles, icons, covers, timestamps
It does not read your Notion comments, your permissions, or anything outside what you shared. It reads that content on your machine to write it into your vault, and it is gone from memory when the sync ends.
What lives on your own computer
Section titled “What lives on your own computer”Your files, on your disk, where you can read and delete them without asking us:
- Your synced notes and attachments, as ordinary markdown and media files
- A local database that remembers which note matches which Notion page
- Your Notion token and licence key, in the plugin’s settings
Uninstall the plugin and delete those, and nothing of N2O remains.
The three services involved
Section titled “The three services involved”| Service | Why |
|---|---|
| Notion | The sync itself. Your token and your page requests go here, from your machine |
N2O (api.n2osync.com) | Signing in with Notion, your licence, and product email |
| Polar, Gumroad | Payment, if you buy. They take your card details, we never see them |
No other external calls are made.
Removing your data
Section titled “Removing your data”Email support@n2osync.com and we will delete your account and licence records.
Your notes need nothing from us. They are already on your computer.
Third-party privacy policies
Section titled “Third-party privacy policies”Children’s privacy
Section titled “Children’s privacy”N2O is not directed at children under 13 and we do not knowingly collect anything from them.
Changes to this policy
Section titled “Changes to this policy”If this policy changes in a way that matters, the date at the top changes with it.
