Terms of use
The agreement between you and Solidarity Lab B.V. for the use of The Fibre and the apps that run on it.
Last updated 24 August 2026
1. Who you are agreeing with
The Fibre is operated by Solidarity Lab B.V., a private limited company established in Rotterdam, The Netherlands. In these terms, “we” and “us” mean Solidarity Lab B.V.; “the platform” means thefibre.app together with the apps served from its subdomains; and “you” means the person using it.
Where you use The Fibre as part of an organisation, that organisation’s workspace admins control your access, and any separate agreement between us and that organisation takes precedence over these terms where the two differ.
2. Access and accounts
- Access is by invitation. An account exists because a workspace admin created it or because you enrolled in something run on the platform.
- You sign in with a single-use link sent to your email address, or with a connected Google account. Keep control of whichever you use — anyone with access to your inbox can reach your account.
- Accounts are personal. Do not share sign-in links, and tell us if you believe someone else has used your account.
- A workspace admin can remove your access to a workspace at any time. That removes your access, not your rights over your own personal data, which are set out in the privacy statement.
3. Acceptable use
The Fibre holds information about real people, much of it entered by you about someone else. That places a duty on you as well as on us. You agree not to:
- record personal data about someone without a lawful basis for doing so, or beyond what the app you are using needs;
- use the platform to send unsolicited bulk messages, or to contact people who have withdrawn consent;
- attempt to reach data belonging to another workspace, bypass access controls, or probe the API beyond the permissions your key or account carries;
- scrape, resell or redistribute the contact records of people you did not collect yourself;
- use the platform unlawfully, or to harass, defraud or endanger anyone.
We may suspend an account or a workspace that is doing any of the above, and will say why when we do.
4. Your content, and who owns it
The records a workspace puts into The Fibre belong to that workspace. We do not claim ownership of them, we do not use them to train anything, we do not profile the people in them, and we do not sell or share them for anyone else’s purposes. We process them to run the service for you, and for nothing else.
You can take them out at any time. Any person with an account can download everything held about them as JSON from the Privacy page, and can request erasure there.
5. Apps
The platform is deliberately split: it holds identity, the contact graph, a thin activity log and consent, while each app holds its own content. Apps we build ourselves and apps built by others reach the platform through the same wall, using a key limited to the permissions their published manifest asked for.
Switching a third-party app on for your workspace is a decision by a workspace admin, and it gives that app access to the data its manifest describes. We review apps before they can be installed at all, but an app you switch on is a relationship between you and its developer: what they then do with the data they are given is governed by their terms, not ours. Switching an app off closes its access; it does not delete what the platform holds.
6. Payments
Where the platform is used to take payment — for a course, an event or a booking — the money is collected through Stripe into the account of the organiser, not into ours. The organiser is the seller and the counterparty for that purchase; questions about a particular payment, refund or invoice go to them. We may charge the organiser a fee on such transactions, which is disclosed to them before it applies.
Refunds and reimbursements are handled by the organiser through the platform. Consumer rights that apply to a purchase apply against the organiser as seller.
7. Availability
The Fibre is actively developed and released frequently. We aim to keep it available and to take backups, but at this stage we do not offer a guaranteed uptime level, and features may change or be withdrawn. We will give reasonable notice before a change that removes something you depend on, and we will not delete workspace data without warning.
8. Liability
The platform is provided as it is. To the extent the law allows, we are not liable for indirect or consequential loss, for loss of profit or business, or for data lost through something outside our control. Nothing here limits our liability for damage caused intentionally or by gross negligence, for death or personal injury, or for anything else that cannot be limited under Dutch law.
9. Ending it
You may stop using the platform at any time, and ask for your personal data to be erased. An organisation may end its use of The Fibre and take its records with it. We may end or suspend access where these terms are breached, where an account is dormant and unpaid, or where we discontinue the service — in the last case, with enough notice to export everything first.
10. Changes to these terms
We will update this page when the terms change and move the date at the top. For a change that materially affects your rights, we will tell account holders by email rather than relying on you to check.
11. Law and disputes
Dutch law applies. If we cannot resolve a dispute between us, it goes to the competent court in Rotterdam, the Netherlands — without prejudice to any right you have as a consumer to bring proceedings where you live.
