Terms of service

1. Who you are dealing with

Derin (“the app”) is owned by Edoardo Pirani and published by Pygocen Ltd under licence. Pygocen Ltd is registered in England and Wales (company no. 16080946), registered office Suite A, 82 James Carter Road, Mildenhall, IP28 7DE, United Kingdom. By installing or using the app you agree to these terms. If you do not agree, do not use it.

2. The pilot

Derin is in a pilot: a test version, offered free to a small number of people for a limited time. It may have bugs, change from week to week, or be paused. Features may be added or removed, and the pilot may end before the app is released. We may ask what you think of it; answering is up to you.

3. Your account

You need to be at least 13 to create an account. Keep access to your phone and its sign-in secure: anyone who can open your Derin account can read your conversations on that phone.

4. Your groups

A group is private to the people in it. Everything you send to a group can be read by everyone in it, including people who join later where the app allows it, and each of them keeps what they received. Only invite people you trust with what you share.

5. How to behave

When using Derin, you agree not to:

• harass, threaten, bully or intimidate anyone;
• share content that is illegal, or that you have no right to share;
• use offensive names, usernames or profile photos;
• pretend to be someone else;
• try to break, overload or get around the app's security or limits;
• use the app for any unlawful purpose.

Messages are end-to-end encrypted, so we cannot see what you send. We act on what people report to us at derin@pygocen.com, and we may suspend or close an account that breaks these terms, and remove a name, username or profile photo that does.

6. Your content

What you write and record belongs to you. You give the people you send it to the right to see and keep it. We do not claim any rights over it, and we cannot read your messages. The app, its design, its questions and this website belong to Edoardo Pirani.

7. Privacy

Our privacy policy explains what we collect, why, and your rights over it.

8. No professional advice

Derin helps people talk. It is not therapy, counselling or medical advice, and it is not a crisis service. If you or someone in your group is in danger, contact your local emergency services.

9. Availability and liability

The app is provided as it is, and during the pilot without any guarantee that it will be available or free of faults. As far as the law allows, we are not liable for any loss arising from your use of it. Nothing in these terms limits liability that cannot be limited by law, or your rights as a consumer.

10. Ending your use

You can stop using Derin and delete your account in the app's settings at any time. We may end your access if you break these terms, or when the pilot ends, and will tell you before we do unless the law or a serious breach prevents it.

11. Disputes and law

If something goes wrong, email derin@pygocen.com first so we can try to put it right. These terms are governed by the law of England and Wales, and its courts have jurisdiction, without taking away any right you have to bring a claim where you live.

12. Changes to these terms

When these terms change, the date at the top changes with them. We will tell you in the app or by email before a significant change takes effect.
