Privacy Policy

How GrowChi handles your information.

This privacy policy explains what personal information GrowChi collects through this website and the GrowChi app, why we collect it, how we use it, and the choices you have.

Who we are

GrowChi Limited is the company responsible for this website, the GrowChi app, and the personal information you choose to submit through the GrowChi waitlist, app registration, app account or enquiry forms. GrowChi Limited is registered in England and Wales with company number 17274302.

What information we collect

When you use the website, join the waitlist, contact us or request early access, we may collect:

Passwords are used to help authenticate GrowChi app accounts. Please keep your password private and do not send it to us by email, message or contact form.

Health, wellbeing and mood information can be sensitive. Please do not send sensitive health information through the website contact form. Only add or connect information in the GrowChi app that you are comfortable using in GrowChi. GrowChi is a wellness companion and not a medical, emergency or crisis support service.

How we use your information

We use personal information to:

AI features and avatar generation

GrowChi uses AI services to power features such as Chi Coach, food analysis and personalised Chi avatar generation.

Chi Coach is an AI companion, not a qualified medical professional. It is not a substitute for professional medical, psychological or clinical advice, or emergency support.

Chi Coach conversations and memory

Chi Coach conversations may be processed by Anthropic to generate responses, under Anthropic's API data retention policies. This data is not used for model training without permission. GrowChi may store recent Chi Coach conversation history to provide continuity across sessions. If you use Chi Pulse, GrowChi may also store selected memory summaries from Chi Coach conversations, such as goals, preferences, struggles or context you share, to personalise future responses. You can clear Chi memory in Profile settings.

Avatar images

Personalised Chi avatars are generated using fal.ai. Your uploaded photo is sent to fal.ai to create the avatar and is not stored by GrowChi as a permanent asset after generation. The generated avatar image is stored securely by GrowChi using Supabase Storage so it can be shown in your account, and is overwritten each time a new avatar is generated. Avatar images are retained until you request account or avatar deletion.

Health and activity data

GrowChi stores the health and activity information you choose to log, including movement, sleep, food, water, relaxation, mood, vibe checks and mental wellbeing check-ins.

If you connect Health Connect on Android, GrowChi may read your steps and sleep duration so these can be logged automatically. GrowChi only requests access to the data types needed for these features.

Data storage and service providers

GrowChi uses trusted third-party providers to run the app, store data and provide AI features. These include:

These providers process data only as needed to provide GrowChi's features.

Our lawful basis

We use your information where you have asked us to contact you, where it is necessary for our legitimate interests in developing and operating GrowChi, and where we need to comply with legal obligations.

Age requirements

GrowChi is currently available to users aged 18 and over. The website is for early interest, waitlist sign-ups, app access interest, rewards partnerships and pilot enquiries. The GrowChi app is not intended for emergency, crisis or medical support.

When you create an account, we may ask you to confirm that you are 18 or over. If you are under 18, please do not create a GrowChi app account or submit personal information through the app. If we become aware that an account belongs to someone under 18, we may close the account and delete the associated data.

International transfers

Some service providers may process information outside the UK. Where this happens, we aim to use providers that apply appropriate safeguards for international data transfers.

How long we keep information

We keep waitlist, enquiry, app account, health, wellbeing, AI feature, purchase, subscription and app activity information for as long as needed to respond to you, manage access, operate the GrowChi app, develop rewards partnerships, improve the product, and maintain appropriate business records. You can ask us to delete your information at any time by emailing support@growchi.co.uk.

Account and data deletion

Full account and data deletion currently requires emailing support@growchi.co.uk. This is because the in-app Clear data from this device button does not delete the full account. It signs you out and removes local device data only. It does not delete your Supabase Auth user, profile, activity logs, synced conversation history, Chi memory or stored avatar image.

When you request full account deletion, GrowChi permanently removes your profile, daily logs, wellness activity data, Chi memory, stored personalised Chi avatar image, push notification tokens, friendships, reports and related app data from GrowChi systems, unless limited records must be retained for legal, security, fraud prevention or financial compliance reasons.

Please email from the address linked to your GrowChi account so we can verify the request. Deletion requests are normally processed within 30 days.

You can also read the public GrowChi account deletion instructions.

Your rights

Depending on the circumstances, you may have the right to access, correct, delete, restrict or object to the use of your personal information. You may also have the right to data portability and to withdraw consent where processing is based on consent.

To exercise your rights, email hello@growchi.co.uk.

Complaints

If you are unhappy with how we handle your information, please contact us first so we can try to help. You also have the right to complain to the UK Information Commissioner's Office at ico.org.uk/make-a-complaint.

Changes to this policy

We may update this privacy policy as GrowChi develops, especially when the app features, AI features, Health Connect use, payments, rewards or data practices change.
