Short version: your files never reach us, and we could not read them if they did.
Copy Shelter encrypts everything on your Mac before it is written anywhere. The key is generated on your machine and is never transmitted, stored by us, or escrowed. We cannot open your backup, and we cannot recover your recovery key if you lose it. That is a deliberate trade and it is why the app makes you confirm you have saved the key before it will continue.
Where your backup goes is your choice: a drive you own, a NAS on your network, or a folder in a cloud account you already pay for. Copy Shelter has no servers holding your data, because it has no storage product at all.
No analytics, no tracking, no advertising identifiers, no profiles, no selling anything to anybody. The app does not phone home to check your licence: licences are verified offline, so your backups keep running whether or not we exist.
If you buy directly, the key we email you is a signed statement that includes the address you bought with. That is how the app can verify it without asking us anything, and it is why it keeps working with no internet connection and no account. It also means two things worth knowing: your email address is stored on your Mac inside the licence, and anybody you give your key to can read it. If that matters to you, buy on the Mac App Store instead, where Apple tells us nothing that identifies you.
We keep purchase records, which are your email address, the licence we issued and the Stripe customer reference, for as long as tax law requires. Ask us at support@copyshelter.com and we will tell you what we hold about you and delete what we are allowed to delete.
