Is syncmarx safe?

Medium risk

syncmarx uploads encrypted bookmark sync archives to the cloud using a bundled decryption key.

When you sync bookmarks, syncmarx compresses and encrypts bookmark data before uploading it to the cloud provider you choose. The encryption key is bundled in the extension code, so the uploaded .syncmarx archive is not protected by a private user-only secret.
