Privacy Policy

1. Who We Are

Heftr is made by twoplus11 LLC, a Missouri limited liability company (twoplus11.com). When this policy says "we," "us," or "our," it means twoplus11 LLC.

2. Data We Do Not Collect

Heftr is built to be completely private:

• Your files are yours. Every analysis and every fix runs locally on your PC. Nothing you open, inspect, or shrink (and nothing about what's inside it) is ever uploaded to us or anyone else.
• Your originals are never modified. Heftr is non-destructive by design: every fix writes a new (smaller) or (compressed) copy, and the original is never overwritten.
• Inspecting and shrinking files is completely offline. The analysis engine never needs the internet.
• No usage analytics. The app does not report how you use it or track what you open.
• No accounts for personal use. Personal use needs no sign-up and no key. (Business-license validation is the one exception; see the next section.)

3. Data We Do Collect

Business-license purchases. If you buy a Business License, you enter your company name, work email, and number of computers in our checkout form. We receive your company name and email so we can deliver your license key and keep a record of the purchase. Payment is processed by Stripe: your card details go straight to Stripe, and we never see or store them.

License validation. When you activate a business license key, Heftr sends the license key and a one-way hash of a Windows machine identifier (a truncated SHA-256 that cannot be reversed) to our licensing server to verify the license. It also sends the device name you choose to show, so you can tell your own computers apart when managing seats. We never receive anything about your files or what's inside them. These requests are hosted on Microsoft Azure, which may keep standard server access logs (such as IP address) for security and operational purposes. Heftr only makes these requests once a business key has been entered.

Update checks. Heftr checks whether a newer version exists: automatically about once a week (you can turn this off), or when you check manually. This is an ordinary HTTPS request to api.twoplus11.com identifying the app, the platform, and the version you are running; like any web request it also carries your IP address. We record that the check happened, with a one-way daily hash of that address rather than the address itself, together with the browser-style identifier your PC sends with any web request, so we can count how many installs are active. Nothing in it describes you or your files. If you then choose to install the update, Heftr downloads the installer from twoplus11.com and verifies its digital signature and version before running it.

4. Where Heftr Stores Things on Your PC

Everything Heftr saves stays inside your own Windows user account, and none of it is transmitted:

• Preferences (window size, language, and appearance settings) in %APPDATA%\Heftr.
• Your business license key and its cached validation result, if you have one, in your user profile folder. The cache exists so the app keeps working without a network connection.
• The application itself in %LOCALAPPDATA%\Programs\Heftr, or in C:\Program Files\Heftr if you chose to install it for everyone who uses the PC.

Uninstalling removes the application. If you want every trace gone, delete the two folders above as well.

5. If You Contact Us

If you email us (for support, beta feedback, or a question about your business license), we receive your email address and whatever you choose to put in your message. If you submit our report form and attach a screenshot, we receive that too. We use this information only to reply to you and to fix the problem. We do not sell or share it.

6. Downloading the App

Heftr is downloaded from our website, which is hosted by a third-party web host. Like any website, the host may keep standard server access logs (such as IP address) for security and operational purposes. This happens at the web-server level when you visit the download page; the Heftr application itself does not transmit anything.

7. Children's Privacy

Heftr is not directed at children under 13, and we do not knowingly collect personal information from children under 13.

8. Your Rights

If you are in the European Union, United Kingdom, or California, you may have the right to access, correct, or delete personal data we hold about you. The only personal data we hold is what you send us by email and, for business-license holders, the company name and email tied to your purchase. You can exercise these rights by contacting jeremy@twoplus11.com. We will respond within 30 days. Deleting your business-license record will deactivate the license.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will update the "Effective date" at the top of this page when we do. We encourage you to review this page periodically.
