How your data is handled
Short and verifiable. No invented badges, only what actually holds.
In short
- Calculations are stored anonymously (inputs and result, no name or contact). Contact details are only attached if you choose to leave them.
- Data sits on Supabase infrastructure, which is SOC 2 Type II and HIPAA compliant.
- Traffic between your browser and the server is encrypted with HTTPS/TLS.
The calculator is anonymous by default
You pick a revenue band, not an exact figure from your P&L. The maths runs in your browser and the inputs and result are stored anonymously so I can see how the calculator is used.
Leaving an email or phone number is optional. Without it, the stored calculation contains nothing that identifies you or your company.
Where the data sits
The database runs on Supabase. Their infrastructure holds a SOC 2 Type II audit and is HIPAA compliant. Those certifications cover the infrastructure the data sits on, not me personally: claiming otherwise would not be true.
Encrypted in transit
The whole site runs over HTTPS/TLS, so nobody reads the data on its way between your browser and the server.
Who can see it
Only I have access to contacts and results. Retention, processing details and your rights are covered in the privacy policy. For anything data related, write to dm@donmarketer.com.
This page describes the real setup, not a security certification of me personally. If you need a formal security questionnaire, write to me and we will go through it together.
