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:

• contact details you submit, such as your name and email address;
• GrowChi app account details, such as your username, email address and password;
• your area, if you choose to provide it;
• your selected interest, such as joining the waitlist, requesting early access to GrowChi, rewards or brand partnerships, or community and organisation pilots;
• anything you choose to write in the message box;
• feedback, bug reports or support messages you send while using GrowChi;
• health and wellbeing information you choose to enter into the GrowChi app, such as steps, activity, sleep, food, water, mood, vibe checks, wellbeing check-ins, goals, streaks, Chi Energy, Chi Crystals and reward activity;
• mood, vibe check and mental wellbeing information you choose to log, which helps Chi reflect how you feel as well as what you did;
• your Chi name, evolution stage and weekly wellness score, which may be visible to authenticated GrowChi users through the global leaderboard. Email addresses and account details are not displayed. Avoid using your real name as your Chi name if you do not want it shown publicly within GrowChi. You can opt out through Profile settings;
• your Chi name, app journey progress, and which wellness areas you have explored and milestones you have reached within the GrowChi experience, including the Chitopia world features;
• avatar setup choices, such as dragon style and personality style selections, used to personalise Chi's appearance and behaviour;
• photos or images you choose to upload for avatar generation, food analysis or other app features;
• friend connections, referral codes, referral activity and reactions you send or receive through the GrowChi social features;
• device push notification tokens and notification preferences, used to send app reminders and friend reaction notifications;
• app interaction data, such as screens visited, taps and feature usage, used to understand funnels, drop-off points and product performance. PostHog session replay is switched off, so GrowChi does not record actual user sessions;
• if you connect Apple Health on iOS or Health Connect on Android, the steps, sleep duration and recorded workout sessions you authorise GrowChi to read when you open the app. GrowChi uses workout type, start and end time, and duration temporarily to exclude duplicate or non-exercise entries and calculate daily exercise minutes. GrowChi stores the resulting daily step, sleep and exercise totals in your GrowChi account, but does not store individual workout sessions. GrowChi does not write health data back to Apple Health or Health Connect;
• purchase and subscription status information, such as Chi Pulse subscription status or Chi Crystal purchases, where provided by Google Play Billing or Apple in-app purchase systems;
• where you explicitly opt in to the Weekly Chi Report, information used to personalise that report, such as your email address, Chi name, subscription tier, logged health and wellbeing activity, goals, progress, milestones and Chitopia activity; and
• basic technical information collected by our hosting and infrastructure providers, such as IP address, browser type, device information, pages visited, server logs and function logs.

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:

• respond to your enquiry;
• manage the GrowChi waitlist;
• create, authenticate and manage GrowChi app accounts;
• operate, test, troubleshoot and improve the GrowChi app;
• reflect your movement, sleep, food, water, mood and wellbeing routines in Chi, Chi Energy, Chi Crystals, progress and reward features;
• generate or personalise Chi avatars, food analysis, Chi Coach responses and other AI-supported app features;
• manage Chi Pulse subscriptions, Chi Crystal purchases and entitlement checks through app store billing systems;
• send and personalise the optional Weekly Chi Report where you have actively enabled it;
• read the steps, sleep duration and recorded workout information you authorise from Apple Health or Health Connect when you open GrowChi, calculate daily exercise minutes, and sync the resulting daily totals into goals, streaks, Chi status, Chi Powers, Chitopia, progress, personalised notifications, Chi Coach and Weekly Chi Report features where applicable;
• understand interest in early access, rewards, brand partnerships, community pilots and organisation pilots;
• improve the website and understand how it is being used;
• support privacy, safeguarding, security and misuse prevention; and
• keep appropriate records for business, security and legal purposes.

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.

If you use Chi Coach, relevant GrowChi daily totals may be included in the information processed by Anthropic to generate a personalised response. These totals may include information previously imported from Apple Health or Health Connect. Anthropic processes this information only as a service provider for the requested Chi Coach feature.

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, exercise, sleep, food, water, relaxation, mood, vibe checks and mental wellbeing check-ins.

If you connect Apple Health on iOS or Health Connect on Android, GrowChi may read your steps, sleep duration and recorded workout sessions when you open the app. GrowChi uses workout type, start and end time, and duration temporarily to exclude duplicate or non-exercise entries and calculate daily exercise minutes. GrowChi stores the resulting daily step, sleep and exercise totals in your GrowChi account, but does not store the individual workout sessions.

GrowChi does not use or store workout routes, heart rate, distance, calorie or location information and does not write health data back to Apple Health or Health Connect. GrowChi does not sell connected health data or use it for advertising, marketing, behavioural tracking, insurance, employment or credit decisions.

Connecting Apple Health or Health Connect is optional and depends on the permissions you choose to grant. You can revoke access through your device settings at any time. Revoking access stops future imports but does not automatically delete daily totals already saved in GrowChi. You can remove those totals by deleting your GrowChi account and associated data.

Weekly Chi Report

The Weekly Chi Report is an optional personalised wellness summary. You can explicitly opt in after your first week with GrowChi or through Profile settings. You are not enrolled automatically.

The report is delivered by email on Wednesdays and reflects the previous Monday-to-Sunday week. GrowChi may use your email address, Chi name, subscription tier, logged health and wellbeing activity, goals, progress, milestones and Chitopia activity to personalise the report.

Core users receive one simple weekly reflection. Pulse users receive a deeper report containing additional metrics, cross-habit patterns and a suggested focus.

Health and wellbeing information may be sensitive. It is only included in the Weekly Chi Report after you actively enable the feature.

You can switch the Weekly Chi Report off at any time through Profile settings or by using the one-click unsubscribe link included in every report. Unsubscribing only disables the Weekly Chi Report. It does not delete your GrowChi account or change your phone-notification settings.

To operate this feature safely and prevent unwanted messages, GrowChi may store report-delivery identifiers and delivery, bounce, complaint, suppression and unsubscribe status.

Data storage, service providers and connected services

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

• Supabase for authentication, app data, database and secure file storage;
• Netlify for hosting, serverless functions, deployment logs and website performance monitoring;
• Resend for delivering the optional Weekly Chi Report by email and managing delivery, bounce, complaint, suppression and unsubscribe status;
• Anthropic for Chi Coach, food analysis and AI text responses;
• fal.ai for personalised avatar generation;
• Firebase Cloud Messaging for Android push notifications and Apple Push Notification Service for iOS notifications. GrowChi does not use Firebase Analytics;
• Apple Health on iOS and Health Connect on Android as optional connected sources for reading authorised steps, sleep duration and recorded workout information when GrowChi is opened. GrowChi converts this information into daily totals and does not write health data back to either service;
• PostHog for event analytics, such as screens visited, taps, funnels and drop-off data. Session replay is switched off;
• Sentry for error monitoring, crash logs and diagnostics; and
• RevenueCat, Google Play Billing and Apple's in-app purchase system for subscription management, if you subscribe to Chi Pulse.

GrowChi’s service providers process data only as needed to provide GrowChi’s features and under GrowChi’s instructions. Apple Health and Health Connect are optional connected data sources controlled through your device permissions.

Our lawful basis

GrowChi relies on different lawful bases depending on why information is used:

• contract, or steps taken at your request before entering into a contract, where processing is needed to provide your account, core GrowChi features and purchases;
• consent for optional connected health data, the Weekly Chi Report and optional communications where applicable;
• legitimate interests for security, fraud prevention, diagnostics and proportionate product analytics, where those interests are not overridden by your rights and interests; and
• legal obligation where GrowChi must keep or use records to comply with the law.

Health, mood and wellbeing information may constitute special-category data. Where a UK GDPR special-category condition is required, GrowChi relies on your explicit consent under Article 9(2)(a).

You can withdraw consent by disconnecting Apple Health or Health Connect, switching off the relevant optional feature, or deleting your account. You can also withdraw consent for the Weekly Chi Report through Profile settings or its unsubscribe link. Withdrawing consent does not affect the lawfulness of processing carried out before consent was withdrawn.

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 delete your account and associated GrowChi data through Profile → Delete account and data. If the in-app process does not work, contact support@growchi.co.uk.

Weekly Chi Report consent status, report-delivery records and unsubscribe status are kept for as long as needed to operate the feature, prove consent where required, honour opt-outs, prevent unwanted messages and meet legal, security or compliance obligations. Suppression records may be retained for longer where needed to make sure we do not send reports after you unsubscribe.

Account and data deletion

You can permanently delete your GrowChi account directly within the app through Profile → Delete account and data.

This permanently removes your GrowChi account and associated data, including your profile, daily logs, wellness activity, Chi memory, reports, push notification tokens, friendships, reactions and stored personalised Chi avatar image. Limited records may be retained where required for legal, security, fraud-prevention or financial-compliance purposes.

Clear data from this device only signs you out and removes locally stored data. It does not delete your online account.

Deleting your GrowChi account does not automatically cancel an active Chi Pulse subscription. Cancel your subscription through the App Store or Google Play subscription settings to prevent future renewal.

If you used Sign in with Apple, GrowChi may remain listed as an authorised app after deletion. You can remove it through Settings → your Apple Account → Sign-In & Security → Sign in with Apple → GrowChi → Delete.

If the in-app deletion process does not work, contact support@growchi.co.uk.

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.

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, Apple Health or Health Connect use, payments, rewards or data practices change.
