Glide

Privacy Policy

Last updated 25 June 2026

Glide is a personal blood‑glucose monitoring app. It collects health information, so we keep this policy plain and specific: what we collect, why, where it goes, how long we keep it, and how you delete it. We do not sell your data, we do not use it for advertising, and we do not track you across other apps or websites.

Who we are

Glide is operated by an independent developer ("we", "us"). For privacy questions, including to exercise any of the rights below, contact [email protected].

Glide is not a medical device and does not provide medical advice. It is a tool for viewing and logging your own data. Always confirm treatment decisions with your glucose meter and your healthcare provider.

What information we collect

We only collect what the app needs to function. There are no ad SDKs and no third‑party trackers.

How we use it

• Show your glucose, trends, and the events you log.
• Fetch new readings from your connected data source.
• Estimate carbohydrates from a meal photo when you ask (see below).
• Sync your settings and shared streams across your devices and any followers you invite.
• Send the alerts and notifications you turn on (lows, rapid changes, signal loss, night alarm).
• Understand which features are used, in aggregate, to improve the app.

We do not use your health data for advertising, profiling unrelated to the app, or any purpose beyond operating Glide for you.

AI carb estimates

When you choose to estimate a meal's carbohydrates from a photo, that photo is sent over an encrypted connection to a third‑party AI provider (OpenRouter and the model it routes to) solely to return a carbohydrate estimate. We route only to providers under a zero‑data‑retention policy: your photo is not used to train models and is not retained by the provider after the estimate is returned. This only happens when you tap to estimate; the app asks for your consent the first time. If you prefer not to use it, simply enter carbs manually.

Who we share data with

We do not sell your personal data. We share it only with the service providers needed to run Glide:

• Amazon Web Services (AWS) — hosting, database, and storage in the United States (region us‑east‑1).
• Your data source (e.g. Dexcom) — to authenticate and fetch your glucose readings.
• OpenRouter — only the meal photos you choose to estimate, as described above.
• PostHog — anonymous product analytics (not linked to your identity).
• People you invite — if you share access to your stream with a follower (e.g. a family member), they can see that stream's glucose and events. You can remove a follower at any time.

We may also disclose information if required by law, or to protect the safety, rights, or security of users.

Data retention & deletion

• Glucose readings and events are kept until you delete the stream or your account.
• Deleted events leave a small marker for up to 60 days so the deletion syncs across your devices, then are removed.
• Meal photos are kept until you delete the event, the stream, or your account.
• Account email and identifiers are kept until you delete your account.
• Anonymous analytics are retained in aggregate and are not tied to you.

You can delete your account at any time from Settings → Delete account in the app. This deletes your sign‑in account and the data keyed to it; if you own a monitored stream, that stream's glucose history, events, and photos are deleted too.

Your rights

Depending on where you live, you may have the right to access, correct, delete, or obtain a copy of your personal data, and to withdraw consent. You can delete your account and data directly in the app. For any other request, email [email protected] and we'll respond within the time required by applicable law. We will not discriminate against you for exercising these rights.

Consumer health data (Washington, Nevada, Connecticut, and similar)

Glide collects "consumer health data" as defined by laws such as the Washington My Health My Data Act. This section describes our practices for that data.

• What we collect & sources: glucose readings (from your connected CGM data source), and the insulin, carbohydrate, meal, and note events you enter — described in detail above.
• Purpose: to provide the app's monitoring, logging, alerting, and optional carb‑estimation features to you.
• Sharing: we do not sell consumer health data and do not share it for advertising. We share it only with the service providers listed above and with followers you choose to invite, for the sole purpose of operating the app.
• Consent: we collect this data with your consent, given when you create an account, connect a data source, and use the app. AI carb estimation requests your explicit consent before any photo is shared.
• Your rights: you may withdraw consent, and access or delete your consumer health data, via in‑app account deletion or by emailing [email protected].

Children

Glide is intended for users aged 13 and older. A parent or guardian may use Glide to monitor a child's glucose, but the account belongs to the adult. We do not knowingly collect personal information from a child under 13 as an account holder. If you believe a child under 13 has created an account, contact us and we will delete it.

Security

All connections use HTTPS. Sign‑in tokens are stored in the device keychain, and signing out clears cached health data from the device. Data is stored on AWS with access controls and encryption at rest. No system is perfectly secure, but we work to protect your information and will notify you and the relevant authorities of a qualifying data breach as required by law.

Changes to this policy

We may update this policy as the app evolves. We'll revise the "last updated" date above, and for material changes we'll provide notice in the app. Continued use after an update means you accept the revised policy.
