Helix Log privacy policy

Helix Horizon Labs, a brand of The Horizon Strategy Group LLC · Effective October 28, 2026 · Applies to the Helix Log Android and iPhone apps.

Helix Log is a reconstitution calculator and dose log. It is built so that your data stays on your device. Helix Log has no accounts, no analytics, no advertising, no third-party tracking and no server of its own. We never see, receive or sell your data.

What Helix Log stores, and where

DataWhere it livesLeaves your device?
Protocols, cycles, vials, your dose log, injection sites, notes and settingsOn your device onlyNo, except in a backup or export file you choose to save, or in your phone's own device backup (see Backups)
Shot remindersScheduled by your phone's own notification systemNo

What you enter can be health-related. It stays on your device as described here. Helix Log only does math on the numbers you enter; it does not suggest doses and is not medical advice.

Backups and exports

From Settings you can save a backup file (JSON) or export your dose log (CSV). You choose where that file goes, such as your files, cloud storage or an email. Once you send a file somewhere, that service's own privacy terms apply. You are responsible for where you keep these files.

Your phone may also include Helix Log's data in its own encrypted backup to your Google account (Android) or iCloud (iPhone), depending on your device settings. Those backups belong to your account; Helix Horizon Labs cannot read them.

This website

This policy is published at helixhorizonlabs.com. The About section of the app links to this website; opening it uses your browser. The site's hosting provider (Netlify) may keep ordinary server logs, such as the address of a device that loaded the page, under Netlify's privacy policy. The Helix Log app itself sends nothing to this website.

Deleting your data

Uninstalling Helix Log deletes everything it stored. On Android you can also clear it in Settings → Apps → Helix Log → Storage → Clear storage. Backup and export files you saved yourself are not touched. Nothing is held anywhere else to delete.

Children

Helix Log is meant for adults and is not directed at children under 13. It does not knowingly collect information from anyone, including children.

Changes and contact

If this policy changes, the new version will be posted at this address with a new effective date. Questions or requests about your data: email Helix Horizon Labs at helixhorizonlabs@gmail.com.
