All XSPLASH apps and sites got a full security check: stricter browser security rules and safer handling of imported backup files in Travel Budget and Monthly Tracker. The Terms of Service are now published at xsplash.app/terms, and the Google Play trader declaration is done for all five apps.
Dossier Vault Pro version 2.0.1.0 is out in Google Play closed testing: the white bar at the bottom is gone and the whole app now follows the dark theme, also at the largest text size. The Google Play page of the free Dossier Vault is updated in English and Dutch, with eight phone screenshots and a Free-versus-Pro comparison. My Vaccine Card now opens without internet, no longer accepts a vaccination date in the future, and its link files for the Android app are back online.
The free Dossier Vault has been rebuilt from scratch as a web app at free.xsplash.app and is on its way to Google Play as an update of the existing app. It now has nine languages, an adjustable interface size, video and audio next to photos, and a one-tap export file to move your cases to Dossier Vault Pro, with photos, video and audio included. Dossier Vault Pro also gained an interface-size button in the top bar. Closed testing is running.
The PDF report in Dossier Vault Pro is now easier for lawyers to read: an overview table on the first page, light cards per entry, photos in a compact grid with figure numbers and fingerprints, people involved shown with their photos, and the automatic export log gathered at the end. You can also move over your data from the free Dossier Vault. Closed testing on Google Play is running, and testers are welcome.
Dossier Vault Pro, the advanced version of Dossier Vault, has been submitted to Google Play for closed testing.

A private family vaccination record tracker built for travel. Every dose, every family member, one offline-first app — your data never leaves your device.
Android is in closed testing on Google Play. To join, email your Gmail address to support@xsplash.app and we will add you.
My Vaccine Card keeps your whole family's immunization history organized and ready — whether you're crossing a border, enrolling in school, or just answering "when was my last tetanus shot?" at the doctor's office. Add a record in seconds: vaccine name, date, dose number, provider, and a photo of the physical card or clinic printout.
Everything is stored locally on your device first, so it works with no signal at an airport check-in counter or a rural clinic. Multiple family profiles keep kids, parents, and grandparents separate but a tap apart, and upcoming-dose reminders mean nothing gets missed between boosters.

Travel Budget Calculator tracks spending across an entire trip in whatever currencies you actually pay in, converting everything to your home currency with live exchange rates so you always know where you stand.

No spreadsheet, no manual conversion math, no losing track halfway through a three-country trip — just open the app, log it, and keep moving.

Dossier Vault helps people build a defensible, organized record of incidents over time — harassment, disputes, safety issues, anything that needs a paper trail that holds up later. Every entry (notes, photos, attachments) is timestamped the moment it's created and hashed with SHA-256, so the record it produces is tamper-evident.
Entries are organized into dossiers, with linked people, attachments, and a dashboard that tracks totals across incidents, reconstructions, and verified records — built for anyone who needs their documentation to be taken seriously.

The advanced version of Dossier Vault: a private vault for recording incidents and keeping evidence in order. Encrypted on your phone, works offline, no account and no ads.
Available on Google Play for Android: €9.99 one-time, no subscription. The free Dossier Vault stays free forever, and you can move your cases to Pro with one file.
Dossier Vault Pro helps you record incidents — noise nuisance, landlord disputes, bullying, harassment, unpaid invoices, defects — and keep the evidence in order. Everything is encrypted on your phone. Nobody at XSPLASH can open your data.
Entries cannot be changed or deleted: you fix a mistake with a correction and the original stays visible. A tamper-evident log shows if anything was altered. When you need it, export one zip for your lawyer with a readable PDF report, the original files and SHA-256 fingerprints.
This app helps you record events and evidence. It is not legal advice. A timestamp shows that something existed at a certain moment, not that its content is true.
Dossier Vault (free) already covers the basics. Dossier Vault Pro adds an encrypted vault, a tamper-evident log, people and witnesses, rich export and much more.
