How your data is handled
Short and verifiable. No invented badges, only what actually holds.
In short
- The calculator runs anonymously. Nothing is stored unless you choose to leave your contact details.
- 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, and the maths runs in your browser.
Leaving an email or phone number is optional. Without it, nothing identifying your company stays behind.
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.
