Your health data stays yours.

Who we are

Hunchwell is an app that keeps a symptom diary for you. You tell it what you ate, did and felt, and it looks for what may be linked. In this policy, “Hunchwell”, “we” and “us” mean the team that makes the Hunchwell app and this website.

This policy covers the Hunchwell app for iPhone and Android, and this website. We treat everything you put into Hunchwell as health data, and this policy is also our consumer health data privacy policy.

What we collect

Data you give us

• Account details, such as your email address, the way you sign in, and a display name if you add one.
• What you log, such as food and drink, symptoms, mood, energy, sleep, medication, activity, readings like blood pressure, and notes.
• Your voice and text when you log an entry.
• Photos of meals or lab reports that you choose to add, and the lab values you confirm.
• Things you choose to tell us, such as symptoms you want to watch or conditions you already manage. We do not treat these as a diagnosis.

Data from your phone and devices, if you connect them

• Apple Health or Android Health Connect, such as sleep, steps, heart rate and workouts. Your phone asks for your permission first, and you choose what to share. We copy this data to your Hunchwell account so we can look for patterns. We never use it for advertising, never sell it and never give it to data brokers.
• Wearables, if you connect one.
• Approximate location, only if you turn on a feature that needs it, such as local weather. We round it to about 10 km and do not store it.

Data we collect automatically

• Usage data, such as which screens you open, to help us improve the app. It does not include health data.
• Error reports when something goes wrong. We remove health data before a report is sent.
• Subscription status. Apple or Google handle payments. We never see your card details.
• Device details needed to send notifications, if you allow them.

How we use it

• To turn what you say or type into log entries for you to check.
• To look for patterns between what you do and how you feel, and to show you the evidence.
• To write summaries of your data and to make reports you ask for, such as a doctor report.
• To send reminders and updates, if you allow notifications.
• To run your account and subscription, and to help you when you contact us.
• To keep Hunchwell secure, and to find and fix problems.
• To improve the app, using data that contains no health information.

We do not sell your data. We do not use your health data for advertising.

How the AI works with your data

Hunchwell uses AI from Anthropic to understand what you say or type, to answer the questions you ask, and to write summaries. Patterns, numbers and scores are worked out by our own code, not by the AI.

• When you log an entry, the words you said or typed are sent to Anthropic to turn them into entries.
• When you ask a question, the parts of your data the answer needs are sent. For example: which symptoms and meals you logged, and whether your sleep, steps or readings from Apple Health or Health Connect were above or below your usual or outside a set range. We do not send the measured values from Apple Health or Health Connect.
• We send the AI only what it needs for each task. We do not send your name or email address.
• Anthropic does not train its models on the data we send.
• Speech is turned into text on your phone. Your voice recording is not sent to us or to the AI.
• The AI suggests. Nothing is added to your log until you confirm it, for example by tapping “Looks right”. An unfinished entry is kept for up to 24 hours so you can finish it later, and then deleted.

Who we share it with

We share data with service providers that run parts of Hunchwell for us, and only so they can do that work:

We may also share data:

• When you choose to, for example when you send your doctor report to someone.
• When the law requires it. We share only what we are legally required to share.
• If Hunchwell changes owner, for example in a merger or sale. Your data would stay protected by this policy, and we would tell you.

How long we keep it

• Your voice is turned into text on your phone. No recording is kept or sent.
• Unfinished entries are kept for up to 24 hours, then deleted.
• Meal photos are deleted after the foods are read, unless you choose to keep them.
• Lab report files are deleted as soon as the values are read. We never keep them.
• Your entries and lab values are kept until you delete them or your account.
• Data from connected services is kept until you disconnect the service or delete your account.
• Backups and providers. After you delete something, copies in our hosting provider's backups are removed when those backups expire. Anthropic keeps the data we send it for up to 30 days for safety checks, and then deletes it.

How we protect it

Your data is encrypted when it travels and when it is stored, and each account can reach only its own data. No system is perfectly secure, but we work hard to protect yours. If a security problem affects your data, we will tell you as the law requires.

Your choices and rights

• Delete an entry in the app: open it and remove it. The entry and the words you said are deleted from your phone and from our servers. If you remove one item from an entry that has more items, the other items and the words you said stay until you remove them too.
• Delete your account in the app, on the You tab. This deletes your account and all your data from our servers and from your phone.
• Disconnect Apple Health, Health Connect or a wearable at any time. We then delete the data that came from it.
• Turn off notifications and location features in your phone's settings.
• Get a copy of your data by emailing us.

Depending on where you live, you may have more rights, such as the right to know what we hold about you, to correct it, or to withdraw your consent. To use any of these rights, email us at[email protected]. We will not treat you differently for using them.

Cycle data

If you log your period, we use those entries to look for patterns between your cycle and your symptoms. Like any entry, the words you say are sent to the AI to turn them into an entry. The cycle patterns we find are kept in your account and are not sent to the AI. Cycle data is never used for analytics or error reports. You can delete a period entry at any time.

Children

Hunchwell is for people aged 18 and over. We do not knowingly collect data from children. If you think a child has given us data, email us and we will delete it.

Where your data is processed

Your data may be stored and processed in the United States and in other countries where our service providers work. When data moves between countries, we use the protections the law requires.

This website

• If you join the invite list, we keep your email address to send you an invite. We delete it if you ask.
• The website remembers if you chose light or dark mode. This stays in your browser.
• This website does not use advertising cookies.

Changes to this policy

If we change this policy, we will update the date at the top. If a change is important, we will let you know in the app or by email.
