DaysAround is a suite of privacy-first iOS applications designed for travelers who need to meticulously track their days spent in various countries and jurisdictions, primarily for purposes of tax residency compliance and personal travel documentation. The apps serve individuals such as British, American, and other non-EU travelers navigating the Schengen Area's 90/180-day rule, digital nomads managing tax residency across multiple countries, and avid travelers who wish to maintain a private record of visited countries. The core purpose is to provide accurate, automated day-counting derived from a user's existing photo library, eliminating the need for manual logging while guaranteeing that all sensitive location and travel data remains exclusively on the user's iPhone, with no external data transmission, cloud storage, or user accounts required.
Traditional methods for tracking travel days, such as spreadsheets or calendar entries, are prone to human error and often abandoned due to the tedious maintenance required, leading to potential compliance risks and personal frustration. For tax purposes, missing a jurisdiction's specific day threshold—like the common 183-day rule or the UK's complex Statutory Residence Test involving ties—can trigger unintended tax residency with significant financial consequences. Similarly, travelers subject to visa rules, like the EU's Schengen 90/180-day limit, risk overstays and future entry bans if they miscalculate. Furthermore, most modern travel map apps and trackers compromise user privacy by continuously collecting GPS location data, syncing it to cloud servers, and requiring logins, turning intimate travel patterns into a data product.
The first major feature group centers on automated, privacy-preserving data ingestion. Instead of requesting live GPS location or manual entry, the apps read EXIF metadata—specifically the date and location data—from the photos already stored in the user's iPhone library. This process happens entirely on-device; the photos themselves are never accessed or uploaded, only the embedded metadata is parsed locally. This technical approach means the system can reconstruct a travel history without any background tracking, providing a reliable, passive record based on where and when the user took pictures. The significance is profound: it delivers automation and accuracy without the pervasive surveillance typical of location-based services, aligning functionality with a strict privacy-by-design philosophy.
The second major feature group involves intelligent rule application and compliance monitoring. For tax residency, the app consolidates every relevant jurisdiction's specific day threshold on a single screen, clearly indicating statuses like 'safe,' 'close,' or 'over' for countries and US states. It is aware of complex rules beyond simple day counts, such as the UK Statutory Residence Test which factors in home, family, and work ties that can lower the residency trigger to as few as 45 days. For Schengen travel, the app calculates the rolling 180-day window, showing exactly how many of the 90 allowable days have been used, how many remain, and the date of the next full reset, providing a single, trustworthy number for travelers to rely on.

Additional capabilities include visualization and personal insight features. The Countries Visited Map automatically generates a world map shaded with the countries the user has visited, derived from the photo metadata, creating a private travel scrapbook. Users collect digital flags and unlock badges (e.g., for visiting 10 countries, 25 countries, or a whole continent) as their travel count increases, adding a gamified element to personal documentation. This map can be exported as a clean image to share socially without exposing the underlying raw data. Furthermore, the apps include planning tools; for instance, users can simulate a future trip to see if it fits within the Schengen 90-day limit or calculate the earliest date a trip would be permissible if currently over the limit.
The product's overall technical approach is defined by its radical local-first architecture. All processing—from reading photo EXIF data, calculating day counts against complex rules, to rendering the visited countries map—occurs solely on the user's iPhone. There is no sync engine, no backup to external servers, and no backend infrastructure because the company deliberately maintains no servers. The apps require no login, account, or Apple ID handshake; they function immediately upon opening. This design eliminates entire categories of data risk, including server breaches, unauthorized data sharing, and vendor data mining, ensuring the user's travel and residency history is physically inseparable from their personal device.
Measurable benefits for users include eliminating the anxiety and administrative burden of manual travel day logging, providing absolute certainty regarding compliance with legally impactful rules like tax residency triggers and visa limits. Users gain a reliable, always-accessible source of truth for their travel movements without sacrificing their personal privacy. The outcomes are practical: avoiding potential tax liabilities, preventing visa overstays and associated bans, and maintaining a detailed, personal travel journal without the risk of that data being exploited, sold, or leaked. The automation saves significant time and mental energy previously spent on spreadsheets or calendar reviews.
Concrete use cases illustrate the workflow. A British digital nomad living in Portugal uses the Tax Residency app to ensure they spend fewer than 183 days in the UK to maintain their Portuguese tax residency, while the app also monitors their days in other European countries they visit for work. An American tourist on a multi-month European tour uses the Schengen Calculator app; before a planned 20-day trip to Italy and France, they input the dates and the app confirms it fits within their remaining 36-day allowance, updating the count automatically after the trip via photos taken. A retiree visiting their 50th country uses the Countries Visited Map app, which automatically adds the new country flag after they take photos there, and they export the map to share with family.
The target users are privacy-conscious travelers, including non-EU citizens (British, American, etc.) navigating Schengen rules, global remote workers and digital nomads managing tax residency across borders, and frequent leisure travelers wanting a private record. The apps integrate solely with the user's local iOS Photo Library, requiring no external software integrations. The tech stack is native iOS development, leveraging on-device frameworks for photo metadata access and local data storage. Pricing is through one-time purchases on the App Store for each individual app (Flags: Schengen Calculator, Flags: Countries Visited Map, Flags: Tax Residency), with no subscriptions or in-app purchases, aligning with the privacy model by not creating ongoing customer relationships that require data retention.
In summary, DaysAround delivers indispensable tools for modern, mobile individuals by transforming the existing photo library into a precise, private travel ledger. It solves critical compliance and documentation problems through intelligent on-device automation while adhering to an uncompromising privacy standard where no travel data ever leaves the user's iPhone. The primary value is peace of mind: knowing exactly where you stand with border and tax authorities, and owning a complete travel history, without trading your personal data for that convenience.
The target audience is privacy-conscious travelers who need to track international days for legal or personal reasons. This includes British, American, and other non-EU citizens traveling in Europe's Schengen Area who must adhere to the 90/180-day rule. It also serves digital nomads, remote workers, and expatriates who manage tax residency across multiple countries and need to avoid triggering tax liabilities by exceeding day thresholds in jurisdictions like the UK, US states, or other countries. Additionally, avid leisure travelers and globetrotters who want to maintain a private, automated record of visited countries without using services that track their location or store data in the cloud are ideal users. The apps are designed for iPhone users who value data sovereignty and seek tools that provide convenience without compromising their personal privacy.
