Terms of Use

Last updated: 16 October 2026

In short: Lens It is free and open source. Use it only with photos you're allowed to use and with people's consent, never for surveillance. It comes with no warranty.

1. Agreement

By using the Lens It website, the Try page, the app or the guest page, you agree to these Terms and to our Privacy Policy. If you don't agree, please don't use Lens It.

2. Who we are, and the software

Lens It is a product of WANDERCOIL ("we", "us"). Its code is free, open-source software released under the GNU Affero General Public License v3.0. If you distribute Lens It, or run a modified version for others to use, you must make your full source code available under the same licence and keep our copyright notice. The face models (YuNet and SFace) are released by OpenCV under the Apache 2.0 License. These Terms add rules about acceptable use; they don't take away the rights those licences give you.

3. If you're a photographer or event organiser

You must have the right to use every photo you load into Lens It.
You are the data controller for your event. You're responsible for complying with the data protection laws that apply to you, such as the Nigeria Data Protection Act 2023.
Tell guests clearly that face matching is available. The printed QR poster includes a short notice for this.
Only let people search with their own face, after they've agreed to the consent note.
Delete face data when you no longer need it. Lens It does this automatically after the period you choose.
Guests who don't want to use face matching must still be able to get their photos another way.

4. If you're a guest or visitor

Only search with your own face, or the face of a child you're the parent or guardian of. Never search for someone else.
On the Try page, only use photos you have the right to use.

5. What you must not do

You must not use Lens It to identify, track or monitor people without their knowledge, to build face databases, to harass anyone, or for any unlawful purpose.

6. No warranty

Lens It is provided "as is", without warranty of any kind. Face matching can miss photos or, occasionally, match the wrong person, so people should always check their results. To the extent the law allows, the makers of Lens It aren't liable for any loss or damage arising from its use.

7. Trademarks

Lens It™, Wandercoil™ and their logos are trademarks of Wandercoil. The open-source licence covers the code only. You may not use these names or logos for your own products, forks or services, or in a way that suggests WANDERCOIL endorses you.

8. Payments

Lens It doesn't process payments. Any sale of photos is between the photographer and the guest.

9. Changes and contact

We may update these Terms and will change the date at the top when we do. Questions: github.com/Wandercoil/lensit/issues.
