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.
