Privacy policy

Readack (“we”) provides email tracking for Gmail. This policy describes what we collect, why, and the choices you have. The short version: we collect the minimum needed to show you when your emails are opened and clicked, we never sell data, and we hash rather than store IP addresses.

What we collect

• Account data. When you sign in with Google we store your Google account id, email address, name, and avatar image.
• Tracking metadata. For emails you choose to track: recipient addresses, subject line, send time, and the links you wrap.
• Tracking events. When a tracking pixel or wrapped link is requested we record a timestamp, the user agent string, and a salted one-way hash of the IP address. Raw IP addresses are never persisted.

What we don’t collect

• We do not read, store, or transmit the bodies of your emails.
• We do not sell or share personal data with third parties.
• We do not use tracking data for advertising.

Recipients

Tracking signals (opens, clicks) are collected on behalf of the sender. Mail clients that proxy or prefetch images (Gmail, Apple Mail) limit what can be inferred; we classify these fetches and present opens as signals with confidence levels, not certainties.

Storage & processing

Data is stored with our infrastructure providers (Vercel, Neon — Postgres in the EU region, and Resend for transactional email). Data is encrypted in transit and at rest.

Retention & deletion

You can delete your account at any time, which permanently removes your account record, tracked emails, recipients, links, and events. Contact us at privacy@readack.com for any data request.

Changes

We will update this page when the policy changes; material changes will be announced in the product.
