We wrote this policy in plain language on purpose. No legal jargon, no hidden surprises — just a clear explanation of what we collect, why, and what you can do about it.
Tax Day Tracker is developed by Ragnar Apps, based in Portugal. If you have any questions about this policy or your data, you can reach us at taxdaytracker@ragnarapps.com.
Trip and earnings data — vessel names, companies, countries, dates, pay rates, and earnings you enter. This is stored on your device. We do not receive or store it, with one narrow exception explained under "Exporting to Excel" below.
Profile information (optional) — if you choose to fill in your profile, we collect:
You don't have to fill in any of this to use the app. Trip tracking, the 183-day counter, the 60-day streak, the SAT timer, backup, and Excel export all work without a profile.
We do not collect:
If you fill in your profile and email address, depending on which boxes you tick, we may use it to:
Each of these is a separate checkbox. Ticking one does not tick the others. You can change your mind at any time in the Profile screen.
Your trip and earnings data stays on your device. We don't have a copy.
Your profile details — only if you fill them in and tick at least one consent box — are sent to and stored in our dedicated Tax Day Tracker database (hosted on Supabase). We store only your name, email, job title, years of experience, and which boxes you ticked. This database is isolated from our other systems and is used solely to contact you in the ways you consented to.
When you use the Excel export feature, your trip and earnings data is sent to our server to generate the spreadsheet file, which is then returned to your device. We do not store this data — it passes through only to build your file, and is not retained afterwards. This step requires an internet connection.
To convert earnings between currencies, the app also requests historical exchange rates from Frankfurter, a free public exchange-rate service. Only a date and currency codes are sent for this — none of your personal or earnings data is sent to Frankfurter.
The app lets you save a backup file of your own data and import it onto another device. This file is created and moved entirely by you (via your own email, messaging, or cloud storage). It does not pass through us.
You can, at any time:
If you're in the EU/EEA or UK, these rights are guaranteed under GDPR. If you're elsewhere, we apply the same standard to everyone regardless of where you live.
If Tax Day Tracker offers a paid tier and you subscribe, your payment is handled entirely by Google Play or the Apple App Store. We do not see or store your card details. We only receive confirmation that you have an active subscription.
Tax Day Tracker is intended for offshore workers, divers, and maritime crew — all of whom must be adults to work in these industries. We do not knowingly collect data from anyone under 18.
If we make significant changes — especially anything affecting the optional consent boxes — we'll notify you in the app and ask you to review your choices again.

This policy is written to be honest and easy to understand. If anything is unclear, please email us and we'll explain it properly — and probably rewrite this section to be clearer for the next person too.

Thanks for using Tax Day Tracker. These terms are kept short and straightforward — here's what you're agreeing to.
Tax Day Tracker is a tool to help offshore workers, divers, and maritime crew track their days spent outside their home country, qualifying days toward tax thresholds (such as 183 days), consecutive-day streaks, and trip earnings.
Tax Day Tracker is a tracking tool, not tax or legal advice. The 183-day and 60-day calculations are based on common rules used by many tax authorities, but tax residency rules vary by country and change over time. Always confirm your specific situation with a qualified tax advisor or accountant. We are not responsible for tax decisions made based on figures shown in this app.
If Tax Day Tracker offers paid features, any subscription is billed through Google Play or the Apple App Store, and the current price and any free-trial terms will be shown to you in the app before you subscribe. You can cancel anytime through your Google Play or App Store account settings. Cancelling stops future billing but does not retroactively refund the current period, in line with Google Play / Apple's standard policies. If we change pricing in the future, existing subscribers will be notified in advance and the new price will apply from the next renewal.
Please don't:
Tax Day Tracker is provided "as is." While we do our best to keep calculations accurate and the app running smoothly, we can't guarantee it will be error-free or available 100% of the time. To the extent allowed by law, we are not liable for any losses arising from use of the app, including (but not limited to) tax penalties, missed deadlines, or lost data.
We may update Tax Day Tracker over time — adding features, fixing bugs, or changing how things work. We may also update these terms. If we make material changes, we'll let you know in the app.
You can stop using Tax Day Tracker anytime by uninstalling the app and, if applicable, cancelling your subscription through Google Play or the App Store.
These terms are governed by the laws of Portugal, without prejudice to any mandatory consumer protection rights you have under the laws of your own country of residence.
Questions about these terms: taxdaytracker@ragnarapps.com
We've tried to write these terms the way we'd want them written if we were the ones reading them — clear, fair, and without hidden catches.
