We share personal data with trusted service providers to operate our product, such as hosting, email delivery, customer support, analytics, and payment processing. These providers are bound by contracts that require appropriate safeguards and prohibit use of your data for their own purposes. If you connect third party accounts, we share the minimum necessary data to deliver that integration. We may disclose information if required by law, to protect our legal rights, or in connection with a corporate transaction. We do not sell personal data.
Your information may be processed outside the UK. When we transfer personal data internationally, we use lawful mechanisms such as adequacy regulations, the UK Addendum to Standard Contractual Clauses, and additional safeguards where appropriate. We assess vendor practices and monitor changes in law to help ensure continued protection.
We keep personal data only as long as needed for the purposes described in this policy, to meet legal obligations, and to resolve disputes. Account content is retained while your account is active. If you delete your account, we delete or anonymize personal data within a reasonable period, subject to backups and legal requirements. Support tickets and transactional records may be kept for a longer period where required by law.
Under UK data protection law, you have rights that include access, rectification, erasure, restriction, portability, and objection. Where processing is based on consent, you may withdraw that consent at any time. To exercise a right, contact us using the details below and we will respond within one month or explain if more time is needed. You can also complain to the Information Commissioner’s Office.
