Privacy policy

KeyId Pro, published by Rumbero Studios. Effective 13 November 2026.

KeyId Pro is a phone app that helps you identify a key from a photograph by comparing it with keys you have saved. This policy covers the app and this website. It says what we collect, why, where it is kept, for how long, and how to have it deleted. Questions go to support@keyidpro.com.

This website

keyidpro.com sets no cookies, runs no analytics and loads nothing from anyone else: its pages, images and styles all come from our own server. The server keeps no access log for this site. There are no forms; if you email us, we have what you send.

What the app collects, and why

Your account

• Your email address. You sign in with a link we email to you, so we need your address to send it and to know which account is yours. The link works once, for five minutes.
• If you sign in with Google (where the app offers it), Google tells us your email address and basic profile: your name, Google's identifier for your account, and a link to your profile picture. We use the email address and identifier to sign you in. We do not receive your Google password.

The keys you save

• Photographs of your keys. Before a photograph is stored it is reduced in size and saved again, and everything a phone writes into a photo file apart from its colour profile is removed, including where the photograph was taken. The reduced copy is the only one kept; the photograph as your phone took it is not.
• A description of each key, worked out from its photograph: the visual features and the bitting (the pattern of cuts along the blade) that identification compares. It is derived from your photograph and is deleted with it.
• What you type in: the key's name, notes and tags, the collection you put it in, and whether it is a favourite.
• A location, only if you add one. You can choose to note where a key belongs, either by using your phone's current location or by typing an address. Nothing is recorded unless you do, and the app asks your phone's permission before using its location. An address you type is looked up by your phone's own location service. A key's location is shown only to you, never to anyone you share your keys with.

Keys you scan to identify

When you scan a key, its photograph is sent to our server, compared with your saved keys, and deleted when the comparison is done. It is not stored. The app keeps a short list of your recent scans, the time and the names of the candidates it showed, on your phone only, and never sends that list to us.

Sharing with your household

If you share your keys with another KeyId Pro account, that person can see your saved keys and their photographs, but not their locations. You can stop sharing at any time, and their access ends at once.

Running the service

Our server records events such as sign-ins and errors against your account's number, not your email address or photographs, so we can keep the service working and fix it when it breaks. Your internet address is used briefly to limit how often sign-in links can be requested. We do not use any of this to profile you.

Your phone's camera and photo library

The app uses the camera only when you take a photograph of a key, and your photo library only when you choose a photograph from it. It does not look through your library.

What we do not do

• We do not sell your information or share it with advertisers or data brokers.
• We do not show advertising, and the app contains no analytics or tracking.
• We do not use your photographs for anything except showing them to you and identifying your keys.

Who else handles it

• Our hosting provider, DigitalOcean, runs the server we store your account, keys and photographs on, and stores our backups. We run the server and the software on it ourselves.
• An email delivery service sends your sign-in links. It receives your email address and the message, only to deliver it.
• Google, if you choose to sign in with Google. Google's own privacy policy covers what it does.

We would disclose information to anyone else only if the law required it.

How long we keep it

• Your account, keys and photographs are kept for as long as you have an account.
• Removing a photograph from a key deletes the photograph file as well as the record of it.
• Deleting your account deletes it at once and for good: your account, every key, every description worked out from them, and every photograph file. There is no waiting period, and we keep no measurements of your keys afterwards.
• Backups are encrypted, and each one is kept for no more than five weeks. Something deleted is gone from our backups once the last backup that held it expires.
• Scan photographs are deleted as soon as they have been compared.

Deleting your account and data

You can remove a key's extra photographs in the app at any time. To delete a key, or your whole account and everything in it, email support@keyidpro.com from the address you sign in with. We will delete it as described above and reply to confirm. Deleting your account from inside the app is coming before KeyId Pro is in the app stores, and this page will say so when it is there.

Your rights

You can ask us for a copy of what we hold about you, to correct it, or to delete it, by emailing support@keyidpro.com. The app can also export your keys' names, notes and tags. If you are unhappy with how we have handled your information, you may also complain to the data protection authority where you live.

Children

KeyId Pro is not directed at children under 13, and we do not knowingly collect information from them.

Changes to this policy

If what the app collects changes, this page changes first, with a new effective date at the top. If a change is significant, we will tell you in the app or by email before it takes effect.
