Privacy Policy
Last updated: February 12, 2026
Introduction
At Sugar Signals, we understand that your family's health data is deeply personal. This policy explains, in plain language, what information we collect, why we collect it, and how we keep it safe.
This Privacy Policy applies to the Sugar Signals mobile application and the website at sugarsignals.com (together, the "Service"). By using the Service, you agree to the collection and use of information in accordance with this policy.
What Data We Collect
We collect the following types of information to provide and improve the Service:
Information You Provide
- Account information: Your name, email address, and password when you create an account.
- Health data entries: Glucose readings, meal logs, insulin doses, notes, and any other data you choose to record in the app.
- Profile details: Information about the person being tracked (such as age or diagnosis date) that you voluntarily provide.
Information Collected Automatically
- Device information: Device type, operating system version, and app version to ensure compatibility and troubleshoot issues.
- Usage data: General usage patterns (such as which features are used most often) to help us improve the app. This data is aggregated and does not identify you personally.
We do not collect location data, contacts, photos, or any data unrelated to the Service's core purpose.
How We Use Your Data
Your data is used to:
- Provide the Service: Store and display your entries, generate insights and patterns, and sync across your devices.
- Improve the app: Understand usage patterns in aggregate to build better features and fix issues.
- Communicate with you: Send important service updates, respond to support requests, and (only with your consent) share product news.
We will never use your health data for advertising, sell it to third parties, or share it with anyone without your explicit consent.
Data Storage & Security
We take the security of your data seriously:
- All data is encrypted in transit using TLS 1.2 or higher.
- All data is encrypted at rest using industry-standard encryption.
- Your data is stored on secure cloud infrastructure with regular security audits.
- Access to your data is strictly limited to authorized personnel who need it to maintain the Service.
While no system is 100% secure, we implement reasonable and appropriate safeguards to protect your information.
Data Sharing
We do not sell your personal data. We may share limited information only in these circumstances:
- With your consent: When you choose to share access with other caregivers or family members through the app's sharing feature.
- Service providers: With trusted partners who help us operate the Service (such as cloud hosting), bound by strict confidentiality agreements.
- Legal requirements: If required by law, regulation, or valid legal process.
Data Retention
We retain your data for as long as your account is active or as needed to provide the Service. Specifically:
- Active accounts: Your data is retained and accessible throughout your subscription.
- Deleted accounts: When you delete your account, we remove your personal data within 30 days. Some anonymized, aggregated data may be retained for analytics purposes.
- Data export: You can export your data at any time through the app before deleting your account.
Children's Data
Sugar Signals is designed to help parents and caregivers manage health data for children. We take children's privacy very seriously:
- Only parents or authorized caregivers may create accounts and enter data on behalf of a child.
- We do not knowingly collect personal information directly from children under 13.
- All children's health data receives the same security protections described in this policy.
- Parents and guardians may review, update, or request deletion of their child's data at any time by contacting us.

You have the right to:
- Access your personal data and receive a copy of it.
- Correct inaccurate or incomplete data.
- Delete your data and account.
- Export your data in a portable format.
- Withdraw consent for optional data processing at any time.
To exercise any of these rights, contact us at legal@sugarsignals.com. We will respond within 30 days.
Changes to This Policy
We may update this Privacy Policy from time to time. When we make significant changes, we will:
- Post the updated policy on our website with a new "Last updated" date.
