Catalog Display Licence

Stamp Identifier & Value (Android) | Identify My Stamps (iOS)

Version: catalog-licence-v1 — Last Updated: August 15, 2026

This licence applies only if you turn on "Allow catalog publication" in the app. If that setting is off, nothing here applies to you and nothing you contribute is ever published. Private contribution ("Contribute scan photos") is a separate choice governed by Section 5 of our Privacy Policy, and it never publishes anything on its own.

1. What you are granting

You grant Viksva, MB a non-exclusive, worldwide, royalty-free licence to store, reproduce, resize, re-encode, and publicly display the photograph you took, together with the verified stamp facts associated with it, in:

• our public stamp catalog (website), and
• the Stamp Identifier / Identify My Stamps apps.

Resizing and re-encoding are included only because a published image has to be converted into web-friendly sizes and formats. They do not permit us to alter what the photograph depicts.

2. What you keep

• You keep ownership of your photograph. This licence transfers nothing. You remain free to use, sell, license, or publish your own photograph however you like, to anyone, at any time.
• It is non-exclusive. Granting it to us does not stop you granting the same rights to anyone else.
• Your identity is not published. The catalog shows the photograph and the stamp facts. It does not show your name, email, contributor identifier, or any hash of your installation identifier — we do not hold your name or email in the first place.

3. What this licence does NOT cover

This is the important limit, and it runs in both directions.

• Not the stamp design. The licence covers your photograph. It does not cover the artwork, engraving, or design of the stamp itself. Copyright in a stamp's design belongs to the issuing postal authority or the artist, not to the person who photographs it, and many modern issues are still in copyright. You cannot grant us rights to the design, and we are not asking you to. We are responsible for our own decisions about which stamps we publish images of, and we will remove any image on a valid rights-holder request.
• Not resale or sublicensing of your photo as stock. We will not sublicense your photograph to third parties as stock imagery, sell it as an image asset, or license it for use outside the catalog and apps described in Section 1.
• Not photographs that are not yours to license. By opting in you confirm the photograph is one you took yourself, or that you otherwise hold the rights to license it as described here.
• Not other people's personal data. Photograph the stamp only. A stamp still on its envelope or postcard can show someone's name, address, or handwriting; please crop that out before scanning. We do not publish images in which personal data of any person is legible — such images fail review and are never published, whatever your publication setting says — and we will remove any published image on request from a person shown or named in it.

4. Publication is never automatic

Opting in makes a contribution eligible for publication. It does not publish it. Every contribution is stored as unreviewed and private, and a photograph can only appear in the catalog after:

• it passes our review, and
• we re-check your publication consent at that moment — not as it stood when you scanned. If you have turned the setting off in the meantime, it is not published.

5. Withdrawing this licence

You can withdraw at any time, from Settings in the app, in either of two ways:

• Turn off "Allow catalog publication". We remove your photographs from the catalog and publish nothing further. Your private contributions stay in place.
• Use "Delete contributed data". This removes everything — the published copies, the private originals, the scan records, and any identification reports you filed.

Withdrawal takes effect prospectively: it ends the licence going forward and obliges us to take our copies down. It cannot undo display that has already lawfully happened, and, as noted above, it cannot reach copies made by third parties while the image was public.

6. Versioning

This licence is versioned (catalog-licence-v1). We record which version was in force when you opted in. If we materially change these terms, publication under the old version stops until you accept the new one. A change here never affects your separate private-contribution consent.

7. Governing law

This licence is governed by the laws of the Republic of Lithuania, consistent with the Terms of Service. Nothing in this licence limits any right you have under the GDPR or other mandatory consumer protection law, including your right to withdraw consent and your right to erasure.
