Planned pricing · not yet on sale
One purchase. Three desktops. No subscription.
Ephemeris Lab is in development. Nothing on this page can be bought yet — this is the pricing we intend to launch with, published early so you can plan.
At launch — 60-day Founder's window
$199–229 USD one-time
List price after the window: $299
- A price-locked upgrade to version two
- First access to development builds
- Your name in the About window, if you want it
- A private channel to the developer
- A quarterly vote on the order of the roadmap
The window runs 60 days from launch, then the price returns to list and the Founder perks close to new buyers. The exact launch figure inside the $199–229 range will be fixed before the store opens.
Afterwards — standard licence
$299 USD one-time
Not a subscription. Not a seat. Not a term.
- One licence covers Windows, macOS and Linux — install on your own desktop machines, not one platform at one price each
- Unlimited charts, unlimited clients, no metering
- Free minor updates within the version you bought
- Future major versions will be a separate paid upgrade — and your existing licence keeps working regardless
- Offline activation, with no account to create
The parts people ask about first.
- Will this become a subscription later?
- No. The licence you buy does not expire and does not convert to a subscription. If a future major version is ever sold separately, the version you own keeps running.
- Is there a free trial?
- Not at launch, and we would rather say so than imply otherwise. A chart-limited trial would block the one thing most people want to evaluate — importing an existing library and seeing whether the charts come across intact. A timed trial gives a one-off user the whole product for free. We may revisit a full-featured timed trial later.
- What about tax?
- Sales tax, VAT and GST will be calculated and remitted by a merchant of record at checkout, which also handles invoicing and receipts. The provider is being finalised and will be named here and in the Terms before the store opens.
- How many machines?
- The licence is for one person's own desktop machines across the three platforms. Concrete activation limits will be stated in the licence terms before sale.
- Refunds?
- There is a refund process — see the refund policy. It is deliberately not the pitch: we would rather earn the sale with the validation record than with a promise to undo it.
- Educational, professional or bulk pricing?
- Not defined yet. If you teach with astrology software or need several licences, get in touch and it will factor into the decision.
Want to know when it opens?
There is no mailing list yet, because there is no system here collecting addresses — this site stores nothing about you. Email [email protected] and you will be told when the Founder's window opens, and nothing else.
