Safety and privacy
We can't read your mail at all. It never passes through us.
No server of its own
The app talks directly to your child's mailbox. Mail, address book, approvals and settings live there and on your family's devices. The devices sync through the mailbox. Juhupost stores the address book, rules and approvals there in encrypted form, with a family key that only your paired devices know.
Who sees what
- Mail from strangers waits for your approval before your child sees it.
- If your child writes to a new address, the mail may come to you first, depending on your settings.
- Mail with approved contacts stays private. You don't see it.
- Settings exist only in the parent area, so your child can't change anything.
Real senders
Juhupost also checks mail from contacts to see whether it's genuine, using the DKIM signature right on the device. Without valid proof, the mail goes to you for review. The app never loads pictures from the internet, and scripts in mails don't run.
Credentials
The mailbox password is stored only encrypted on your devices (Android Keystore). You pair more devices with an encrypted QR code and a six-digit number, so a photo of the QR code alone is not enough.
Ads and tracking
Juhupost contains no ads and no service that analyses usage. Apart from the mailbox, the app connects for the empty wake-up call of the instant alert (with Family, can be switched off). It goes through Google, contains only the device's identifier and is stored nowhere.
If you agree, the app also sends crash reports. They only contain technical details about the error, no emails, names or addresses. We need them to make Juhupost more stable and secure (privacy policy).
What Juhupost can't do
Juhupost protects the mailbox inside the app. A mail from a stranger stays in the inbox until a device with Juhupost next syncs and moves it to the review. Anyone who looks into the mailbox with another program during that time will see it, so don't share the password. The app can't spot every forgery, and it doesn't replace talking with your child about their mail.
Remove without a trace
Everything Juhupost creates in the mailbox lives in a folder called “Juhupost”. One button in the parent area removes it. Afterwards it's a perfectly normal mailbox for any mail program.
