1. Information We Collect
Depending on how you use Hashi, we may collect the following categories of information:
- Account and identifier information, such as an anonymous app account identifier, referral data, reward status, and subscription customer identifiers used to keep your account working across our services.
- Profile information you choose to provide, such as your first name, age range, diagnosis status, goals, and reminder preferences.
- Health and wellness information you manually enter, such as symptoms, lab values, medications, supplements, habits, notes, and other thyroid-related tracking information. This information is primarily stored locally on your device unless you export it or another feature specifically requires server support.
- HealthKit data you explicitly authorize Hashi to read, such as sleep or workout information. Hashi currently requests read access only.
- Purchase or subscription information related to premium features, where applicable.
- Documents or images you choose to import for lab tracking, which are stored in the app’s local storage on your device unless you export or share them.
2. How We Use Information
We use your information to:
- Provide, maintain, and improve Hashi and its features.
- Store and display the health and wellness information you choose to track.
- Sync account, referral, reward, and subscription status across our service providers.
- Generate summaries, insights, exports, or visualizations based on your entries.
- Support subscriptions, anonymous account access, troubleshooting, and reliability.
- Protect the app, prevent misuse, and maintain security.
- Comply with legal obligations when required.
3. Health and Sensitive Data
Some information you enter into Hashi may be considered sensitive personal information or health-related information. We treat this data with heightened care.
Hashi is designed to help users organize and review personal wellness information. Any summaries, insights, trends, highlights, or exported reports generated by the app are informational only and should not be relied upon as medical advice or as a clinical decision-making tool.
You are responsible for deciding what information you enter into the app and whether to share any exported material with a clinician or other third party.
5. Data Retention
We retain personal information for as long as reasonably necessary to provide the app, fulfill the purposes described in this policy, comply with legal obligations, resolve disputes, and enforce agreements.
Daily logs, lab entries, imported lab report files, and many profile settings may remain stored locally on your device until you remove the app data, delete the app, or delete that content yourself.
If you request deletion of server-stored information, we will take reasonable steps to delete or de-identify anonymous account, referral, reward, or subscription-linked data we control, subject to legal, security, backup, fraud-prevention, or operational retention needs.
6. Security
We use reasonable administrative, technical, and organizational safeguards intended to protect your information. However, no method of storage, transmission, or security is completely guaranteed. You use the service at your own risk and should keep your device secure.
7. Your Rights and Choices
Depending on your location, you may have rights to:
- Access certain personal information we hold about you.
- Request correction of inaccurate information.
- Request deletion of certain personal information.
- Withdraw consent where processing is based on consent.
- Request a copy of your data where applicable.
To make a request, contact us using the email listed below. We may need to verify your identity before completing certain requests.
8. Children’s Privacy
Hashi is not intended for children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through the app, please contact us so we can review and delete it where appropriate.
9. Changes to This Policy
We may update this Privacy Policy from time to time. If we make material changes, we may revise the “Last updated” date and take additional steps where required by law. Your continued use of Hashi after changes become effective means the updated policy will apply.
