Frequently Asked Questions
How does day counting work?
Atrium is UK-first. For the UK Statutory Residence Test, it tracks UK midnights, tax-year windows and relevant SRT ties using confirmed journeys and supporting evidence. Other jurisdictions may use different counting rules.
Is my location data stored permanently?
Location evidence is used to support a journey record, not to replace it. Atrium stores user-confirmed travel records and selected supporting evidence such as GPS check-ins, boarding passes or receipts. You can review and delete records from the app.
How do I add a trip manually?
Use the add journey flow to enter departure and arrival details, then attach supporting documents such as boarding passes, hotel receipts or GPS evidence.
Which jurisdictions are supported?
Atrium is designed primarily for UK tax residence analysis under the Statutory Residence Test (SRT), with supporting travel and day-count views for other common jurisdictions.
How do I delete my account?
Go to Profile → Settings → Account → Delete Account. This will permanently remove all your data. You can also email privacy@atrium.tax to request deletion.
Can I export my data?
Yes. You can export your travel history, UK day counts, assumptions and attached evidence as a PDF or CSV suitable for review by your tax adviser.
