Terms of Use

Last updated 12 November 2026

These terms are the rules for using PinStellation. By creating an account you agree to them and to the Privacy Policy.

What PinStellation is

An app for keeping track of the pins you own, want and trade. It names a pin from a photo, lets you browse the catalog other collectors build, and keeps a journal of your trades.

Your account

• One account per person. Keep your password to yourself.
• Tell us if you think someone else is using your account.
• You can look around without an account. Keeping pins needs one.

What you add

Your photos and notes stay yours. When you add a pin or a photo to the catalog, you let PinStellation show it to other collectors in the app, keep it in the catalog, and use it to make recognition better. It stays in the catalog, without your name, if you delete your account. Add only photos you took or have the right to share.

While Add my scans to the catalog is on (it is until you turn it off in Profile › Privacy), a clearer cutout of a pin you scan may be added to the catalog as a photo you added, on the same terms. Only the pin's cutout is used, never the photo you took. Scan only pins you're happy to share a picture of, or turn it off.

What isn't allowed

We have zero tolerance for objectionable content and abusive collectors. Don't post or write:

• sexual, violent, hateful or shocking photos or words
• harassment, threats or bullying
• someone else's personal details
• spam, scams or ads
• pretending to be someone else
• artwork you don't have the right to share, when its owner objects

We remove anything that breaks these rules, and we can pause or end the account of the person who posted it, without warning.

Reporting and blocking

On a pin's page you can report a name or a photo and block the person behind it. A person reads every report and takes down anything that breaks these terms. Blocking is quiet: the other person isn't told.

Trading

Trade matching is for people 18 and over. Trades happen in person, pins for pins: never ask for or send money. Meet somewhere public, and read Trading safely before your first trade. You can report or block any trader, offer or trade from its menu, and a block hides you from each other everywhere in trading. We can pause the trading of anyone who breaks these rules.

Takedowns

If you own the rights to artwork shown in the catalog and want it removed, email support@pinstellation.com with the pin's name and what you own. We'll take it down.

Recognition is a best guess

PinStellation suggests which pin is in your photo. It can be wrong. Check before you rely on it, especially in a trade.

Scans and matching

Matching a pin from a photo is what PinStellation is for. To measure how well it works and make it better, each scan keeps a fingerprint (a list of numbers worked out from the pin's cutout, not the photo), the pins the app showed, the pin you chose and how you found it, and how the scan was made. This is part of using the app, for every account. The Privacy Policy says what's kept and for how long. Photos and cutouts from your scans are kept for training only while Help improve recognition is on. A cutout added to the catalog through Add my scans to the catalog is a catalog photo, kept as What you add says.

No warranty

PinStellation is provided as it is, without promises that it will always work, be available, or be free of mistakes. As far as the law allows, we aren't responsible for losses from using it, including trades you make.

Ending

You can delete your account at any time with Delete account at the bottom of Profile, under Account. We can end an account that breaks these terms. We can also change or stop the app.

Changes

If these terms change, the date at the top changes too. Using the app after a change means you accept the new terms.
