Privacy Policy
BlockLift Ltd ("BlockLift", "we") builds the BlockLift app and runs blocklift.app. This policy explains what we collect, why, and the choices you have. It covers the app and the website. We are the data controller. Company number NI743143, registered at 6 Ballyhenry Grove, Newtownabbey, Northern Ireland, BT36 5BQ. Contact: hello@blocklift.app.
What we collect
- Beta list (website). Your email address, when you join the beta, plus the browser's user-agent string for abuse prevention.
- Account. Email address and an authentication identifier. If you sign in with Apple or Google, we receive the identifier and email those services share.
- Profile and preferences. What you tell the app to build your plan: age, sex, bodyweight, training days, experience, goals, equipment, injuries and movements to avoid, sport.
- Training data. Sessions, sets, reps, loads, notes, check-ins, personal records, and your messages to the coach.
- Health data (optional, with your consent). Sleep and heart-rate variability from Apple Health or Health Connect, used only for readiness and recovery decisions. Workouts you complete can be written back to those services if you enable it.
- Diagnostics. Crash reports and error events (via Sentry) that include device model, OS version and a correlation identifier. No health data is included in diagnostics.
Why we use it
- To run the service you asked for: building and adapting your training plan, logging, progress, and coaching. Lawful basis: performance of a contract.
- To send your beta invite and beta updates. Lawful basis: consent, which you can withdraw by emailing us.
- To keep the service secure and prevent abuse. Lawful basis: legitimate interests.
- Health data is processed only with your explicit consent, which you give in the app and can revoke in the app or your device settings at any time.
Coaching and AI
The coach uses large language models from Anthropic and Google to write plans, feedback and chat replies. We send them the training and profile context needed for the response. We do not use your data to train those models, and our contracts with those providers prohibit them from doing so.
Who we share it with
Only processors that run the service on our behalf: Supabase (database and authentication), Railway (hosting), Anthropic and Google (coaching models), Sentry (diagnostics), and Apple and Google (sign-in, app distribution, health platforms). We do not sell personal data and we do not share it with advertisers.
Where it is stored
Our infrastructure runs in the United States and the European Union. Where data leaves the UK we rely on the UK International Data Transfer Addendum and the providers' standard contractual clauses.
How long we keep it
- Beta list emails: until the beta ends or you ask us to remove you.
- Account and training data: while your account exists. Delete your account in the app and it is removed within 30 days, except where the law requires us to keep records.
- Diagnostics: 90 days.
Your rights
You can ask for a copy of your data, correct it, delete it, restrict or object to how we use it, and take it elsewhere. Email hello@blocklift.app. You can also complain to the Information Commissioner's Office at ico.org.uk.
Children
BlockLift is for people aged 18 and over. We do not knowingly collect data from anyone younger.
Changes
We will post any changes here and update the date at the top. If a change materially affects how we use your data, we will tell you in the app or by email.
