Borderly - Residency Tracker

Track every day, prove every day. Automatic GPS day-counting with audit-grade cryptographic proof.

Track every day. Prove every day. Know exactly where you stand.

Borderly is the tax residency tracker built for high-stakes decisions. Automatic GPS day-counting paired with cryptographically verifiable proof of where you were: every single day, every single jurisdiction.

WHY BORDERLY

Most apps count days. Borderly counts days and timestamps them with the same RFC 3161 authority used by enterprise compliance teams and accepted in court. If a state tax auditor ever asks where you were on May 12th, you have the answer signed, sealed, and impossible to fabricate after the fact.

AUTOMATIC TRACKING • GPS-based detection of state and province boundaries • All 50 U.S. states and every Canadian province • Offline jurisdiction resolution for U.S. states, no signal required • Battery-efficient: built on significant-location-change APIs • Configurable check-in cadence, from a few times a day to hourly

EVIDENCE THAT HOLDS UP • RFC 3161 timestamps available on every record • Hash-chained presence records - tamper-evident by design • Optional daily blockchain anchoring • Professional-ready PDF reports with cryptographic verification • Independent verification links your auditor can open without an account

GOALS THAT MATCH REAL TAX RULES • Minimum-day goals (e.g., "183 days in Florida") • Maximum-day limits (e.g., "Under 30 days in New York") • Ratio, target, percentage, and domicile-establishment goals • Smart alerts before you cross a threshold

PLAN AHEAD, NOT JUST LOOK BACK • Scenario planning with a tap-and-drag to paint calendar • Model future trips against your goals • See projected year-end totals blending actual + planned days • Switch between scenarios without losing your tracked data

EVIDENCE VAULT • Upload receipts, boarding passes, photos, and supporting documents • Tied to specific days and jurisdictions • Soft-delete with grace period

BUILT FOR YOU AND YOUR ADVISOR • Share read-only access with your CPA or tax attorney • One-time verification links for third-party auditors with usage limits • Bring your professional onto Borderly - professional portal access is free for them • Audit log of every third-party view of your data • Generate audit-ready PDF reports and CSV exports in seconds

YOUR DATA, YOUR CONTROL • Our business is built on trust, and we take that duty seriously • Your data is yours. You decide who sees it and what they can do with it • Scoped sharing for your CPA, attorney, or auditor, revocable anytime • Encrypted in transit and at rest, with an audit log of every third-party view • We don't sell your personal data or share it with data brokers - it wouldn't sit right with us
