Privacy Policy
Custom Arts Ltd built the Feeltracker app as a Freemium app. This SERVICE is provided by Custom Arts Ltd at no cost and is intended for use as is.
This page is used to inform visitors regarding our policies with the collection, use, and disclosure of information if anyone decided to use our Service.
If you choose to use our Service, then you agree to the collection and use of information in relation to this policy. However, the Feeltracker app does not collect or store any personally identifiable information (PII) on our servers. All data generated by the app is stored locally on your device or synced with your personal iCloud account. We do not have access to this data.
Information Collection and Use
For a better experience while using our Service, the Feeltracker app may utilize iCloud for data syncing across your devices. This data is stored securely in your iCloud account, and we do not collect or access any personal data from you. You can control iCloud data through your device's iCloud settings.
The app does use a small number of third-party services that may collect aggregated, non-identifiable data (such as usage analytics or crash reports) to improve the app experience. We do not use any advertising or ad-network services.

iCloud Syncing
Feeltracker stores and syncs user data across devices using Apple’s iCloud service. This allows you to access your health diary across your Apple devices seamlessly. Data stored in iCloud is protected by Apple’s privacy and security measures. We do not have access to this data. For more information on Apple’s iCloud privacy, please refer to Apple’s Privacy Policy.
Log Data
In the case of an error or crash in the app, we collect log data through third-party services such as Firebase Crashlytics. This log data does not include personally identifiable information and is used only to diagnose and fix errors to improve the app’s performance.
Cookies
The Feeltracker app itself does not use cookies. However, the app may use third-party services or libraries that use “cookies” to collect non-personally identifiable data. You have the option to either accept or refuse these cookies and know when a cookie is being sent to your device. If you choose to refuse the cookies, you may not be able to use some portions of the Service.
Service Providers
We may employ third-party companies and individuals for the following reasons:
- To facilitate our Service;
- To provide the Service on our behalf;
- To perform Service-related services; or
- To assist us in analyzing how our Service is used.
These third-party services may collect non-personally identifiable information as described above, but they are obligated not to disclose or use the information for any other purpose.
Security
We value your trust in providing us your information through the use of iCloud. We strive to use commercially acceptable means of protecting it. However, please remember that no method of transmission over the internet or method of electronic storage is 100% secure and reliable, and we cannot guarantee its absolute security.
Links to Other Sites
This Service may contain links to other sites. If you click on a third-party link, you will be directed to that site. Note that these external sites are not operated by us. Therefore, we strongly advise you to review the Privacy Policy of these websites. We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.
Children’s Privacy
The Feeltracker app is not intended for children under the age of 12. We do not knowingly collect personally identifiable information from users under 12 years of age. If we become aware that a child under 12 has provided us with personal information, we will take steps to delete it immediately.
If you are a parent or guardian and believe that your child under 12 has provided us with personal information, please contact us so that we can take appropriate action.
Profile Information (Optional)
You can optionally save a small profile in the app with your name, date of birth, and gender. This is completely optional — all the core tracking features work without it, and you can edit or delete your profile any time from inside the app.
Profile details are stored the same way as your other data: on your device and, if you use iCloud, in your private iCloud account. We never upload them to our servers, and we never share them with anyone for advertising or marketing.
If you choose to use an AI feature (like chat, insights, or tailored feedback powered by OpenAI or Apple Intelligence), the app can include the relevant bits of your profile with the request — usually your first name, age (worked out from your date of birth), and gender — so the AI can give you more relevant answers, for example age-appropriate health guidance or the right pronouns. This only happens when you actually use an AI feature, and only the profile fields needed for that request are sent. Turn off AI features or clear your profile any time to stop this.
Apple Health (Optional)
The Feeltracker apps can connect with Apple Health (HealthKit), but only if you switch it on. The apps won’t read from or write to Apple Health until you give permission in iOS, and you can take that permission back at any time in iOS Settings.
When it’s on, the apps can read relevant history from Apple Health (such as blood pressure, heart rate, weight, sleep, and State of Mind) and save new readings you record back to HealthKit. Everything happens on your device. Apple Health data never goes through our servers, is never sent to any third party, and is never seen by Custom Arts Ltd.
For details on how Apple handles Health data, see Apple’s Privacy Policy.
Apple Intelligence (Optional)
On recent devices with a compatible version of iOS, iPadOS, or macOS, the Feeltracker apps may offer optional features powered by Apple Intelligence — Apple’s built-in AI. These only run when you choose to use them.
Apple Intelligence runs on your device where possible, and uses Apple’s Private Cloud Compute for heavier requests. In both cases, Apple says your data isn’t stored, isn’t visible to Apple, and isn’t used to train Apple’s models. Custom Arts Ltd doesn’t receive, store, or see any Apple Intelligence requests or responses.
For details, see Apple’s Privacy Policy.
OpenAI API (Optional)
Some AI features in our app are optionally powered by the OpenAI API, which can look at what you type (for example, a question you ask the AI, a journal entry, or specific readings) and send back feedback, suggestions, or insights. These features are strictly opt-in — you have to actively choose to use them, and you can turn them off any time inside the app.
When you use an AI feature, only what’s needed for that request is sent to OpenAI: (a) your prompt or question; (b) the specific data you’re asking about (for example the blood pressure or mood readings you want explained); and (c) if you’ve saved a profile, a bit of context — usually your first name, age (worked out from your date of birth), and gender — so the AI can tailor its reply (for example, appropriate pronouns or age-relevant guidance).
Under OpenAI’s API policies, data sent through the API isn’t used to train their models, and is only kept for a short period for abuse checks. We don’t keep your AI prompts or responses on our servers — they only live on your device.
You can read the full policy here: OpenAI Privacy Policy.
By using an AI feature you agree that the relevant data (including any profile details you’ve chosen to save) will be sent to OpenAI and processed under their policies. Please don’t type anything into the AI that you wouldn’t be comfortable sending under those terms.
No Advertising
The Feeltracker apps don’t show ads, don’t plug into any ad networks or advertising SDKs, and don’t share your personal, profile, or health data with advertisers. We don’t use AdMob, ad exchanges, ad-attribution SDKs, or ad-targeting analytics. The apps are funded entirely by optional premium subscriptions and one-time purchases, handled by Apple through the App Store.
Your Rights and Choices
You stay in control of everything you put into the app:
- See and export your data. Any profile info (name, date of birth, gender), readings, and journal entries can be viewed and exported from inside the app as a PDF, Excel, or JSON file, any time.
- Fix things. Any entry or profile field can be edited right in the app.
- Delete. You can delete any single entry, your whole profile, or all app data from inside the app. Removing the app and its iCloud backup in your iOS Settings clears everything. Because we don’t keep a copy on our servers, there’s nothing extra for us to delete on your behalf.
- Change your mind. Optional features — Apple Health, Apple Intelligence, OpenAI-powered AI features, and analytics/crash reporting — can each be switched off in the app or iOS Settings without affecting the rest of the app.
- Stop processing. If you don’t like how something in this policy works, you can stop using that feature or stop using the app.
These rights apply everywhere. They line up with laws such as the EU/UK GDPR and the California CCPA/CPRA. We don’t sell your personal information, we don’t “share” it in the CCPA/CPRA sense, and we don’t use it for cross-site behavioral advertising.
Legal Basis (EU/UK GDPR)
Where the EU or UK GDPR applies, we rely on your consent for optional features you switch on yourself (Apple Health, Apple Intelligence, OpenAI-powered AI features, profile data used to tailor the AI, and analytics/crash reporting), and on our legitimate interest in keeping the app working, fixing crashes, and preventing abuse. You can withdraw consent at any time by turning the feature off — doing so doesn’t affect anything that happened before.
Custom Arts Ltd is the data controller for personal data processed by the app.
Where Your Data Lives
Your personal and health data lives on your device and in your own iCloud account — you’re in charge of it. A few optional third-party services we use (Firebase, RevenueCat, OpenAI) are run by providers based in the United States and may process some data there. Where needed, they rely on the Standard Contractual Clauses and/or the EU-US Data Privacy Framework to move personal data out of the EU/UK. If you’d rather none of your data was transferred, you can turn off the matching optional features.
How Long Data Is Kept
We don’t keep copies of your app data on our servers. Your data stays on your device and in your iCloud for as long as you have the app installed and iCloud backup on. Firebase Crashlytics/Analytics data is kept by Google for our project’s default retention period; RevenueCat keeps purchase/receipt data for as long as you have an active subscription and as tax law requires; OpenAI keeps API request data according to their API data-usage policy. Turning a feature off or deleting the app stops further collection.
Changes to This Privacy Policy
We may update our Privacy Policy from time to time. You are advised to review this page periodically for any changes. Material changes will be highlighted on this page, and continued use of the app after an updated policy takes effect constitutes your acceptance of the updated policy.
This policy is effective as of 2026 April 20th.
