Privacy Policy

InjectBuddy is a free dosage-calculator suite built and operated by the InjectBuddy team. You can use the calculators anonymously with no account at all. You can also optionally create an account to save your protocols and track your data — in which case we store that data for you. This policy explains exactly what is and isn't stored in each case, and how to access or delete your data.

Using the calculators (no account)

The core calculators require no account and store nothing about you:

If you create an account

Accounts are optional. If you choose to sign up (by email and password, or with Google), we store the data needed to provide the account features. It is held in our database (Supabase) and tied to your account so we can show it back to you:

We do not sell your data and we do not use your saved health data for advertising. It exists only to power the account features you asked for. So your saved protocols load instantly, a copy is also cached in your browser's localStorage on your own device; that copy is removed when you sign out.

Accessing and deleting your data

While signed in, open Account → Settings → Account, where you can:

If you have any trouble, contact us and we will help.

Optional community survey

From time to time InjectBuddy invites visitors to take an optional, anonymous community usage survey, shared by a direct link. It is the one place where information you submit is stored — and only because you opt in:

Analytics

This site uses four analytics tools:

If you use a browser extension that blocks analytics scripts, the calculators will function identically — analytics is passive and has no bearing on site functionality.

Cookies and local storage

InjectBuddy does not set advertising or cross-site tracking cookies. If you sign in, a standard session cookie keeps you logged in; the analytics tools above may set their own cookies or identifiers as described.

The site uses your browser's localStorage on your own device for things like your theme choice, guide content you have viewed, and — when you are signed in — a cached copy of your saved protocols so they load instantly. This stays on your device; the cached account copy is cleared when you sign out.

Third-party services

InjectBuddy loads fonts from Google Fonts and React from jsDelivr. These are standard CDN resources. Their respective privacy policies govern any data handling on their end. No sensitive data is sent to these services — only the standard HTTP request to load the resource.

Children

InjectBuddy is intended for adults. You must be 18 or older to create an account, and we do not knowingly collect data from children.
