Privacy Notice
Last updated 14 November 2026
Who is responsible for your data
GainzTracker (gainztracker.com) - Contact: support@gainztracker.com.
What we keep
- Your account: the name you choose, your email address, and your password stored in a scrambled form that we cannot read.
- What you log: your exercises, sets, reps and weights, your routine and notes, your diet list, your bodyweight readings, and the targets and goal you set in the diet planner.
- Your settings: colours, tracker name, units and similar choices.
- Payments: if you pay, PayPal tells us the amount, the date and a transaction number, which we store against your account. We never see or store card details.
- Security records: the internet address (IP) behind failed log-ins and some forms, kept for 24 hours to block abuse.
Bodyweight and diet entries can say something about your health. We only use them to show you your own progress and to work out the targets and diet sheets you ask for. Only add them if you are happy for us to store them. You can remove any entry yourself.
Why we keep it
- To provide the tracker you signed up for (our contract with you).
- To store bodyweight, diet and training entries that you choose to enter (your consent, which you can withdraw by deleting the entries or your account).
- To keep accounts secure and stop abuse (our legitimate interest).
- To keep payment records as the law requires.
We do not sell your data, show adverts, or use your data for marketing by anyone else.
Who else handles it
- Hosting: the site and its database run on servers in our hosting provider's data centre.
- PayPal: takes payments. PayPal's own privacy policy applies to what you give them.
- Anthropic (Claude): when you add a food that is not in our list, the food name is sent to Anthropic's AI service to get typical nutrition figures. When you build a diet sheet, your chosen food names with their figures, your calorie and protein targets, your goal and number of meals are sent. Your name, email address and bodyweight are not sent. Anthropic handles this under its commercial terms and may process it outside the UK.
Cookies and device storage
We use only what the site needs to work: a cookie that keeps you logged in during a visit, and one that keeps you logged in on a device for up to 90 days if you tick that box. Your browser also remembers which drop-down boxes you left open. We do not use advertising or tracking cookies.
How long we keep it
We keep your account and what you log for as long as you have an account, including while a membership has lapsed, so it is there if you come back. Ask us to delete your account and we will remove it and everything in it within 30 days. Payment records are kept for as long as tax law requires, which is about 6 years. Entries to the How Strong Are You calculator are anonymous and are kept.
Your rights
You can ask for a copy of your data, ask us to correct it, delete it, or stop using it, and you can withdraw consent at any time. Email us from the address on your account. If you are unhappy with how we handle your data you can complain to the Information Commissioner's Office at ico.org.uk.
Children
Accounts are for people aged 16 and over.
Changes
If this notice changes, the date at the top changes with it, and we will email members about anything significant.
