Binder is for adults aged 18 and over. This policy explains how we seek to ensure only adults can access the Platform, supporting our Children’s Access Assessment and Online Safety Act duties.

We aim to use age assurance that is highly effective at correctly determining whether a user is a child, meaning (per Ofcom) that it is technically accurate, robust, reliable and fair. We do not rely on self-declaration of age alone, which is not highly effective.

Age assurance is carried out via Stripe identity verification. We collect the minimum necessary and, where possible, receive only a confirmation that the user is 18 or over rather than copies of identity documents.

We minimise age-assurance data: we retain only confirmation of age and its date; underlying verification data is held by Stripe under its own controls. This is consistent with our Privacy Policy, Data Retention Schedule and DPIA.

We seek to apply age assurance fairly and to avoid unfairly excluding adults who can prove their age by legitimate means; we will provide a route to challenge an incorrect age decision and to request human review.

We may re-verify age where there is reason to doubt a user is 18+, and we act on reports that a user may be under 18 (see the Community Guidelines and Privacy Policy).

We record our age-assurance approach and review it as technology and Ofcom guidance develop, and at least annually.
