IBID.

Privacy policy

Your library is yours.

Effective 26 September 2026 · applies to Ibid. for iPhone

In short: Ibid. has no account, no analytics, no advertising and no tracking. We do not receive, collect or store any of your data. Your library stays on your device, in your own iCloud only if you turn on backup, and in your Obsidian vault only if you set up sync. When you look a book up, its ISBN, or its title and author, is sent to public library catalogues.

Who is responsible

Ibid. is published by Derwan Consulting Ltd (“we”), a company registered in England and Wales, number 08617945, registered office 167–169 Great Portland Street, 5th Floor, London W1W 5PF. It is made by Andre Astovasadourian. To get in touch, see Support.

What we collect

Nothing. Ibid. has no server of its own and contains no analytics, crash-reporting, advertising or other third-party code. We cannot see your books, passages, notes, photos or how you use the app.

What stays on your device

Your books, passages, notes, reading status, ratings, projects and cover photos are stored on your iPhone or iPad. They are included in your device’s own backups, as for any app.

What is sent when you look up a book

To find an edition, Ibid. sends the book’s ISBN, or the title and author you typed, to these public catalogues:

Ibid. also fetches cover images from these catalogues by catalogue number, including automatically when the app opens for books that are missing one. As with any website, these services see your device’s IP address when they answer. Nothing else is sent: never your passages, notes, reading status, projects or photos. Their handling of requests is governed by their own policies.

Optional iCloud backup

If you turn on Automatic backup, Ibid. saves recovery copies of your library to your own iCloud Drive, in a container belonging to the app. This is stored by Apple under your Apple Account; we have no access to it. It is off until you turn it on.

Obsidian sync

Obsidian sync is optional and off until you set it up. When you choose your Obsidian vault:

Where your vault goes next is up to you. If your vault is synced by a service such as Obsidian Sync, iCloud Drive, Remotely Save or Synology Drive, that service copies the notes Ibid. writes, including your passages, to wherever it stores your vault, under its own terms and privacy policy. Ibid. does not talk to these services and we have no access to them. To stop, remove the connection in Ibid.; the notes already in your vault stay until you delete them.

Exports and sharing

When you export or share, Ibid. hands over exactly what you chose to the place you chose: a file, another app through the share sheet, or your photo library. What happens next is governed by that place.

Keeping and deleting your data

Children

Ibid. is not directed at children and collects no data from anyone.

Changes

If this policy changes, the new version will be published here with a new effective date. If Ibid. ever starts collecting data, that will be stated here and on its App Store page before it happens.
