Privacy Policy

What we collect

• Contact form: your name, email address, subject and message.
• Waitlist: your email address and optional lab name. Existing entries are retained after signup opens.
• Accounts and labs: your name, email, hashed password, sessions, lab profile/logo, timezone, memberships and invitations.
• Lab records: the clients and their contacts, projects and criteria, mixes, and equipment that authorized lab members enter.
• Free tools: the tool name and time when a complete result is calculated. Calculator inputs stay in your browser and are never sent to us.
• Page visits: we count visits on our own servers without third-party analytics. For public pages, we store the page path, IP address, country and browser user-agent for up to 90 days to measure visitor traffic and protect the service. We also derive a daily salted visitor code for aggregate reporting. Signed-in, opted-out and automated-crawler visits are excluded from this traffic log.
• Country lookup: country is estimated offline from GeoLite2 country data created by MaxMind, available at maxmind.com.
• Search and AI crawlers: we record user-agent claims, page path and response status, separately from visitor counts.
• Subscriptions: when sold, billing details are collected and processed by Paddle.com, our Merchant of Record, under its own privacy policy.

Signing in

For security, we record sign-in time, method, result, device and country. Sign-in emails are sent by our email provider, Resend.

How we use it

We use your information to answer your messages, provide and improve the service, and meet legal obligations. We do not sell personal information.

Analytics

We keep raw page visits, including IP addresses and browser user-agents, and crawler hits for 90 days. Sign-in events are kept for 12 months. Daily totals are kept without the daily anonymous identifiers.

Who we share it with

Only with service providers that help us run ProofGrit, such as hosting, email delivery and payment processing, and only as needed for that purpose, or when the law requires it.

How long we keep it

We keep contact messages as long as needed to handle your request and any follow-up, and other data for as long as your account or legal obligations require.

Your choices

You can ask us to access, correct or delete your personal information by contacting support@proofgrit.com. We will respond within a reasonable time.

Changes

If we change this policy we will update the date at the top of this page.
