Backspark is run by Blink Label, Inc. This is everything we hold about you and what we do with it. Questions go to support@backspark.io.
What we can't see
- What's in your files.
- Their names, or the folders they're in.
- Your 24 words, or the key made from them.
All of that is encrypted on your Mac before it leaves. How it works
What we hold
- Your email address, which is how you sign in.
- Your Mac's network name, when it last connected, and how much it has stored.
- Your encrypted backup, and the size and time of each upload.
- Whether you're on a trial or a plan, and the id Stripe gives your payments. Your card goes to Stripe and never reaches us.
- Emails you send us.
To limit sign-in attempts we count them by network address. We keep that as a hash, for no more than a day.
What the app sends
The app talks to us to sign in, to get permission for each upload and download, and to check your plan. It looks for updates on backspark.io a few times a day. It sends no analytics, and nothing about how you use it.
A report you save from This Mac stays on your Mac until you choose to email it. It has no file names, paths, keys or tokens in it.
This website
No analytics, no ads and no trackers. Cloudflare serves the pages and sees the address each request comes from, as any host does.
Who else is involved
- Backblaze
- Stores your encrypted backup.
- Amazon Web Services
- Runs our server and holds the account details above.
- Stripe
- Takes payment, and holds your card and billing details.
- Resend
- Sends our emails to you.
- Cloudflare
- Serves this website.
We don't sell what we hold, and we don't share it with anyone else unless the law makes us. If it does, all we can hand over is what's listed above, and your backup stays encrypted.
How long we keep it
For as long as you have an account. When a trial or a plan ends, your backup is deleted 30 days later. Storage keeps deleted data for up to 30 days more, in case something was deleted by mistake, and then it's gone.
To see what we hold, correct it, or have your account and backup deleted sooner, write to us.
