Data Hash Secure
Hash List
Hash contact columns locally. Share lists without sharing emails.
Create your account here, subscribe, then download the desktop app. Contact data never leaves your computer — Stripe only handles billing.
Create account & subscribe
One step on this site. We’ll email a confirmation link (branded via Resend). After you confirm, continue to Stripe Checkout. Then sign in to the desktop app with the same email.
How it works
- Sign up on datahashsecure.com and complete Stripe Checkout.
- Install Hash List on Windows or macOS and sign in.
- Open a spreadsheet, pick a column, choose MD5 or SHA-256.
- Save a hashed CSV for your marketing partner — processed locally.
Download
After you subscribe, install Hash List and sign in with the same email.
- macOS — Apple Silicon (ZIP, v0.1.0) — unzip, drag Hash List to Applications. Unsigned: right-click → Open the first time if macOS blocks it.
- Windows — Installer (EXE, v0.1.0) — unsigned test build; SmartScreen may warn until code-signed.
Manage subscription
Cancel or update billing from the desktop app Account screen (Stripe Customer Portal).
