You can delete your account from inside the app at any time:

1. Tap your profile avatar (top right) to open Profile.
2. Go to Account and tap Delete account.
3. Confirm. Your account and all associated data — including protocols, labs, wellbeing and sleep data, injection-site logs, photos and AI history — are permanently removed.

Deleting your account does not cancel an App Store or Google Play subscription — cancel that separately (see below). If you can't sign in, email us from your account's email address and we'll delete it for you.

App Store and Google Play subscriptions are billed and managed by Apple or Google, so they're cancelled in your store settings:

• iPhone / iPad: Settings → [your name] → Subscriptions → Biohack Tracker → Cancel Subscription.
• Android: Google Play Store → profile icon → Payments & subscriptions → Subscriptions → Biohack Tracker → Cancel.
• Bought on our website: use the manage-subscription link in your receipt email, or email us and we'll cancel it for you.

Cancel at least 24 hours before your renewal date to avoid the next charge. You keep Pro access until the end of the period you've paid for. After that you keep the Lifetime unlock that came with Pro, so all your tracking and data stay available; only the Pro features stop.

Sign in with the same Biohack Tracker account, open the Pro / subscription screen and tap Restore Purchases. Make sure you're signed in to the same Apple ID or Google account that made the purchase. If Pro still isn't unlocked after a minute, close and reopen the app, then contact us.

App Store and Google Play payments are processed by Apple or Google, so refund requests for those go through them: Apple at reportaproblem.apple.com, or Google Play via your order history. Bought on our website? Email us and we'll handle the refund. Your rights under Australian Consumer Law are not affected.

• Check your spam, junk, or Promotions folder for an email from Biohack Tracker.
• On the verification screen, tap Resend Email and wait a few minutes.
• Double-check the email address you signed up with for typos.

Still nothing? Email us from that address and we'll help.

On the sign-in screen tap Forgot password and enter your account email. We'll send a reset link (check spam if it doesn't arrive). We can't see or send you your existing password — it's stored only as a secure hash.

Your data is stored in your private, password-protected account, encrypted in transit and at rest. We don't sell it, don't use it for advertising, and it is never used to train AI models. AI features send only the information needed for your request to our AI provider, and only when you use them.

You can view all of your data in the app, and Pro members can export clinician-ready PDF reports. In many countries you can also download a full copy yourself: Profile → Privacy → Download my data. To request a full copy of your personal information, or a correction, email us from your account's email address. Full details are in our Privacy Policy.

No. The app helps you organise and understand your own records — it is not a medical device and doesn't diagnose conditions, recommend treatments, or suggest doses. AI summaries, lab patterns, the dose reference indicator and the injection guide are educational only; the dose reference only compares a dose you enter with published ranges — the decision is always yours and your clinician's. Always discuss results and any changes with a qualified clinician. In an emergency, call your local emergency number (000 in Australia, 911 in the US/Canada, 999/112 in the UK).

The app is free to download. A one-time A$4.99 Lifetime unlock (no subscription) gives you all tracking: protocols and supplements, alarm mode and calendar sync, the injection map and how-to guide, the supplement scanner, the Workout library (500+ workouts with 72 animated exercise how-tos), Wellbeing check-ins and sleep sync, manual lab entry with "worth discussing with your GP" patterns, lab PDF import and Photo AI scan, charts, templates, the compound library and progress photos. Pro adds the AI features — the AI coach, AI bloodwork and trend summaries and clinician PDF export — for A$7.99/month or A$79.99/year, and it includes the Lifetime unlock for good: cancel Pro and you keep the unlock and all your data. After unlocking you can try the coach free (6 questions + Biohack analysis) before deciding.

Open the Pro / subscription screen (or your Profile) and tap Have a code?. On iPhone this opens Apple's offer-code sheet; on Android it opens Google Play's redeem screen. Enter the code there — it's applied by the store, not typed into our app. Promo codes are for new subscribers and may be time-limited. After any introductory period, the subscription renews at the standard price unless you cancel.

Yes — fair-use limits keep the service fast and affordable. At the moment: 40 Biohack coach messages a day (400 a month), 10 AI analyses a day (bloodwork, trends, photo and protocol reviews), and 3 Photo AI scans a day (5 a month). Daily limits reset at midnight and monthly limits on the 1st. Reaching a limit never affects your tracking, lab grading or reminders. AI features only run after you allow them to share your data with our AI provider — you can switch this off any time in Profile → AI features.

Open Trends → Wellbeing and tap Connect Apple Health (iPhone) or Connect Health Connect (Android), then choose which data to share on your phone's permission screen. Any tracker that shares sleep with Apple Health or Health Connect works — for example Apple Watch, Oura, Whoop, Garmin, Fitbit, Samsung Health, Withings and most sleep apps.

• Sleep and overnight recovery data is summarised on your phone; only one summary per night is saved to your account.
• Hours you type in yourself are never overwritten.
• Nothing showing? Check that your tracker's own app shares Sleep with Apple Health / Health Connect, and that Biohack Tracker is allowed to read it (iPhone: Settings → Privacy & Security → Health; Android: Health Connect → App permissions).
• To stop syncing, go to Profile → Connected apps → Stop. Logging out also stops it.

Wearable readings are device estimates. Any "worth mentioning to your GP" note is educational, not a diagnosis.

In More → Injection map, tap How to inject for an animated, step-by-step guide for each body area — site preparation, skin technique, commonly used angles and equipment, and when to seek medical advice. It's general education only: always follow your prescriber's, pharmacist's or product's instructions, and ask a health professional to show you if you're unsure.
