Most online office suites do not support E2EE, meaning the cloud provider has access to everything you do. The privacy policy may legally protect your rights, but it does not provide technical access constraints.
We don't recommend using the [E2EE App](https://apps.nextcloud.com/apps/end_to_end_encryption) for Nextcloud as it may lead to data loss; it is highly experimental and not production quality. For this reason, we don't recommend third-party Nextcloud providers.
**CryptPad** is a private-by-design alternative to popular office tools. All content on this web service is end-to-end encrypted and can be shared with other users easily.
**Please note we are not affiliated with any of the projects we recommend.** In addition to [our standard criteria](about/criteria.md), we have developed a clear set of requirements to allow us to provide objective recommendations. We suggest you familiarize yourself with this list before choosing to use a project, and conduct your own research to ensure it's the right choice for you.
!!! example "This section is new"
We are working on establishing defined criteria for every section of our site, and this may be subject to change. If you have any questions about our criteria, please [ask on our forum](https://discuss.privacyguides.net/latest) and don't assume we didn't consider something when making our recommendations if it is not listed here. There are many factors considered and discussed when we recommend a project, and documenting every single one is a work-in-progress.
In general, we define collaboration platforms as full-fledged suites which could reasonably act as a replacement to collaboration platforms like Google Drive.
- Open-source.
- Makes files accessible via WebDAV unless it is impossible due to E2EE.
- Has sync clients for Linux, macOS, and Windows.
- Supports document and spreadsheet editing.
- Supports real-time document collaboration.
- Supports exporting documents to standard document formats (e.g. ODF).
#### Best-Case
Our best-case criteria represents what we would like to see from the perfect project in this category. Our recommendations may not include any or all of this functionality, but those which do may rank higher than others on this page.
- Should store files in a conventional filesystem.

**PrivateBin** is a minimalist, open-source online pastebin where the server has zero knowledge of pasted data. Data is encrypted/decrypted in the browser using 256-bit AES. It is the improved version of ZeroBin. There is a [list of instances](https://privatebin.info/directory/).
