4. Cookies

We use essential cookies to maintain your session and authenticate you across the platform. We do not use advertising or tracking cookies. Essential cookies are required for the service to function and cannot be disabled.

Under UK GDPR, essential cookies do not require explicit consent as they are strictly necessary to provide the service you have requested. We do not use any cookies that track your behaviour across other websites or for advertising purposes.

5. Third-Party Services

We use the following third-party services to operate SendSight:

  • Supabase: Authentication and database hosting

6. Data Security

We implement industry-standard security measures to protect your personal information. All data is encrypted in transit using TLS and at rest using AES-256 encryption. API keys are stored using encryption and are never exposed in plain text. However, no method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.

7. Data Retention

We retain your account information for as long as your account is active. If you delete your account, we will delete your personal information within 30 days, except where we are required to retain it for legal or regulatory purposes. Aggregated, anonymised data may be retained indefinitely.
