Transparency and privacy
Your email is the only info we have about you and we don't share it with anybody else. You can actually see our live website analytics here the same way we see them.
How does that work, you ask?
To maintain confidentiality and safety of your data, files and folders are transferred exclusively through your devices.
That means that if you are copying a file from e.g. Google Drive to OneDrive, your device will download that file from Google Drive and then upload it to OneDrive. Once the successful upload has been confirmed, the downloaded file will be deleted.
Simply put, you can count on us making sure that your files never touch our servers.
And in more detail…
mementō application requires access to your remote storage such as Google Drive or OneDrive. Once that access is granted, a token is sent from the remote provider to the device. The information that you have added a remote account is then encrypted and sent to servers so that your other devices can ask you to sync remote storage. Data on the servers cannot be accessed without the encryption key that lives on your devices.
When you are adding a new device, a secure channel is established using QR codes and the keys are exchanged between the devices. New device can then download the information about remote storage services you use from the mementō server and decrypt them. Once that is done, you are asked to allow the new device to access the data on the remote service.
Our encryption is based on the well known libsodium library.
How we make sure that your data is intact during the transfer
We calculate a hash while data is being transferred and then compare that hashes of destination and target sides. If the hashes are matching we know the transfer was successful.
