Tax Residency

Privacy Policy

Last updated: June 4, 2026

Summary

Tax Residency is designed to process personal information primarily on the user's device. Hypatia does not operate an analytics, advertising, or location-history server for the app, and does not sell or share app data for advertising or marketing.

Information processed by the app

The following information may be processed locally by the app, depending on which features the user enables:

• Location data: device location, visit points, inferred country codes, and daily country summaries used to calculate time spent in each country.
• Motion and activity data: optional motion signals used to improve low-power location updates and detect movement or stops.
• Photo library metadata: optional analysis of geotagged photos, initiated by the user, to reconstruct past country stays. Photos are not uploaded to Hypatia.
• App-generated data: manual entries, notification thresholds, excluded countries, monitored areas, backup settings, device labels, diagnostic logs, and app preferences.
• Notifications: local notifications configured by the user to warn about stay-limit thresholds.
• Widget data: compact on-device summaries shared with iOS widgets through the app group container.

Purpose and legal basis

The app processes data to provide country stay calculations, timeline views, manual corrections, local alerts, widgets, import/export, and optional private iCloud backup. Where GDPR applies, processing that depends on protected device permissions is based on the user's consent through iOS permission prompts and in-app settings.

On-device processing and iCloud backup

Core calculations are performed on the device. Optional iCloud backup stores backup files in the user's own Apple iCloud account and is governed by Apple's terms and privacy policy. Hypatia does not receive the user's iCloud backup files.

Data sharing

Hypatia does not share Tax Residency location history, photo metadata, stay summaries, or app records with third-party advertising or analytics providers. If the user contacts support, only the information included in that support request is processed so that Hypatia can respond.

Retention and deletion

Local app data remains on the device until the user deletes it, resets the app database, imports replacement data, or uninstalls the app. Optional iCloud backup files remain in the user's iCloud account until deleted by the user or by app backup retention settings.

User controls

• Location, motion, photo library, and notification permissions can be changed in iOS Settings.
• Tracking options, thresholds, excluded countries, backup settings, and manual entries can be managed inside the app.
• Users can export their records, import a backup, or reset local data from the app settings where available.

International transfers

Hypatia does not transfer app records to its own servers. Optional iCloud features may involve Apple's infrastructure and international transfers under Apple's own legal terms and safeguards.

Children

Tax Residency is intended for adults and is not directed to children. Hypatia does not knowingly collect personal information from children through the app.

Rights and requests

Where applicable, users may have rights to access, correct, erase, restrict, object to, or receive a copy of personal information processed by Hypatia. Because app records are stored locally or in the user's iCloud account, many controls are available directly on the device. For privacy requests, contact info@hypatia.site.

Changes

Hypatia may update this Privacy Policy as the app changes. The latest version will be published on this page with the date above.
