Company overview
The company behind the software
Ars Vitae Pty Ltd trades as Hex Pro. We are an Australian company with two lines of business, software and games, and one approach to both: modest prices and care for the people who use what we make.
Who we are
Hex Pro at a glance
Hex Pro is the trading name of Ars Vitae Pty Ltd, an Australian proprietary company. Our software is released under the Hex Pro name, and our games under Hex Games.
Today that means a privacy-first file sync service, apps for iPhone, iPad and desktop, two free browser tools and a first game. Our websites share a single codebase with common design and translation systems, and keeping overheads that low is what lets prices stay modest.
Products on this site are described as they are today. Anything unfinished is labelled that way.

Operations
How the company runs
Status labels mean what they say
A product is only marked coming soon once it is feature complete, and anything still planned is labelled as planned.
One source for every price
Prices on apps.hex.pro come from a single registry, so a figure cannot drift between pages or languages. Where an app offers a one-time price and a subscription, both are shown and the choice is yours.
Data held briefly
Our websites are hosted on servers in Sydney and Queensland, Australia. Contact form messages are deleted within 24 months, and the hashed network details used to stop spam are erased within seven days. Our privacy policy names every provider involved, including those that may process data outside Australia.
Read our privacy policyAustralian privacy law as the floor
We handle personal information under the Privacy Act 1988 (Cth) and the Australian Privacy Principles, and our policies describe what we do in practice.
The business model
How modest prices pay their way
Each product's price follows what it costs us to run. That keeps prices low without relying on advertising or selling data.
One-time purchases where nothing needs running
An alarm clock has no servers behind it, so Sol Alarm will be sold once, with a monthly option for people who would rather spread the cost. Nepali Companion will be a single purchase too.
Subscriptions where there is a running cost
kcalc.ai's meal analysis runs on servers in Australia, most of them our own, and its subscription will pay for that work. It will cost less bought at kcalc.ai than through the App Store, because the payment processor there takes a smaller cut, and the app will say so on its own paywall.
Free, with the costs in public
Hex NFC is free. Its development costs are published, and donations are counted against them in the open.
Free to self-host, with hosting as a paid service
Citadel's self-hosted version will always include every feature. Hosted plans, when they arrive, will charge for running the service.
No third-party advertising
No Hex Pro app carries a third-party ad network. The only thing any of them promotes is another Hex Pro app.
Maintenance
Looking after things for longer
We plan for years of repair work after each launch, and some of that is already in writing.
Citadel's self-hosted edition will stay complete and free, and you can export every file whenever you like. Hex NFC's source licence converts to Apache 2.0 on 1 June 2030. Our browser tools have no runtime dependencies, which leaves less underneath them to go stale.
Learning
Documentation and teaching
Two of our apps are for learning a language, and the Hex NFC user guide is online before the app itself. CustomTD will ship with example mod packs covering each system a mod can change, so modders start from working examples.
Longer-term work
Two areas we are moving into
Neither is a product, and we have not set any dates. When there is something to show, it will appear on this site with a status label like everything else.
Building and evaluating our own models
Most of kcalc.ai's meal analysis already runs on GPU servers we own in Australia, and Infinilang works with models you run on your own machine. We want to understand models from the training data up, including what each one learned from and where it goes wrong, and to hold that work to the same privacy and pricing rules as everything else we make.
Security research
Hex NFC reads and writes password-protected and encrypted tags, and Citadel encrypts files before they leave your computer. Both only work if the protection holds. We will be studying how protection like this fails, starting with our own software, and reporting what we find responsibly.
