Privacy Policy
Last updated November 14, 2026
Bighaus is a strength-training coach made by Galanta Tech, LLC (“we”, “us”). This policy covers the Bighaus iPhone app, the Bighaus connector for AI chat apps such as Claude and ChatGPT, and this website. It explains what we collect, why, who sees it, and what you can do about it. Bighaus is offered in the United States.
The short version
- We collect what it takes to coach you: your account, your training profile, and the workouts you log.
- In the app, what you say to the coach is sent to Anthropic’s AI, Claude, so it can understand you and reply. We send it for that and nothing else.
- We don’t sell your data, show ads, or use tracking or analytics tools.
- You can ask for a copy of your data, or for us to delete it, at any time.
What we collect
Your account
You sign in with Apple or Google. We receive your email address and the name on that account. If you use Sign in with Apple and hide your email, we receive Apple’s relay address instead. Sign-in runs on Google’s Identity Platform (Firebase Authentication), which keeps your account record, how you sign in, and when. Bighaus is invite-only for now: we create your account from the email address your invite went to.
Your training profile
Your name, time zone, and training program, and your gender if you give it to us (the coach uses it for pronouns). It also holds notes we write for the coach, such as an injury to train around.
Your workouts
Each workout you’re given and each one you log: exercises, weights, reps, effort, how a set felt, and your notes. Also your warm-up and recovery, check-ins about energy, sleep and mood, flags you raise such as pain or an injury, body measurements if you log them (weight, body-fat percentage, skeletal muscle mass), and problems or feedback you report through the coach.
Your conversations in the app
What you say or type to the coach, the coach’s replies, and the steps it took (such as logging a set) are saved as a transcript of each day’s session, along with how much AI processing each reply used.
Your voice
When you hold the talk button, your iPhone turns your speech into text with Apple’s speech recognition. It runs on your device when it can. When it can’t, Apple processes the audio on its servers under Apple’s privacy policy. We receive the text only, never audio.
Requests to our servers
We keep a record of each request the app or a connected AI chat app makes to our servers: when it happened, what it asked for, what we answered, and the name of the app that sent it. These records are how we find and fix problems, such as a set that didn’t log. When you connect an AI chat app, we also keep that app’s name and the addresses it uses to sign you in. Your access tokens are stored only in a scrambled (hashed) form.
This website
This website sets no cookies and loads nothing from anyone else. Our host keeps standard request logs (IP address, browser, page and time).
How we use it
- To build your workouts, prescribe your loads, and track your progress.
- To run the coach conversation in the app.
- To answer your questions and to find and fix problems.
- To keep Bighaus secure and prevent misuse.
We don’t use your data for advertising, and we don’t sell it or share it for advertising.
Who sees it
- Our team. The people who run Bighaus can see your profile, workouts, request records, and app conversations. We look at them to coach you, help you, and fix problems.
- Anthropic. In the app, each time you talk to the coach, your message, the day’s conversation so far, and the profile and workout details the coach needs (such as your name, program, and today’s workout) are sent to Anthropic’s Claude to produce the reply. Anthropic handles it as our service provider under its commercial terms, which don’t let it train its models on this data.
- Google. Our servers, database, and sign-in run on Google Cloud and Firebase. Our servers and database are in the United States (Oregon).
- Apple. Sign in with Apple, and speech recognition when it can’t run on your device. If you test the app through TestFlight, Apple may share crash reports and any feedback you send with us.
- Expo. The app checks Expo’s servers for updates, which gives Expo your IP address and basic app and device details.
- Your AI chat app, if you use the connector. If you use Bighaus from Claude, ChatGPT or another AI chat app, that app’s maker receives your workouts and our responses as part of your chat, under your account with them and their privacy policy. We see only the requests the app sends us, not the rest of your chat.
- When the law requires it, or when it’s needed to protect someone’s safety. If Bighaus is ever sold or merged, your data would move with it, and this policy would still apply to it.
How long we keep it
- Your account, profile and workouts: as long as your account is open.
- App conversations: as long as your account is open.
- Request records: as long as your account is open.
- Technical logs at our cloud provider, including IP addresses: about 30 days.
When you delete your account, we delete all of this, request records included, within 30 days, except anything the law requires us to keep. Copies in our backups are gone within 90 days.
Your choices
- Get a copy. Ask us and we’ll send your profile, workouts and conversations in a common format.
- Fix something. Tell the coach, or tell us.
- Delete your account. Email us from the address you sign in with and we’ll delete your account and its data. Deleting from inside the app is on its way.
- Disconnect an AI chat app. Remove the Bighaus connector in that app, or ask us to cut it off.
We answer every request within 30 days. Write to info@galanta.ai.
Security
Everything travels over encrypted connections and is encrypted at rest by Google Cloud. Access tokens are stored only in hashed form, and the database can be reached only through Google’s authenticated connector. No system is perfectly secure. If you find a problem, please tell us.
Health information
Bighaus is not a medical service, and it doesn’t read Apple Health. The injuries, notes and check-ins you share are used only to coach you.
Children
Bighaus is for adults 18 and over. We don’t knowingly collect data from anyone younger. If you think a child has given us data, contact us and we’ll delete it.
Changes
If we change this policy, we’ll update the date at the top. For significant changes, we’ll tell you in the app or by email before they take effect.
