HealthSaveWho you buy from
Keltek AI makes HealthSave and HealthSave Observatory. In these terms, "we" means Keltek AI.
Paddle sells the product to you. Paddle is our merchant of record: it takes the payment, charges sales tax or VAT where it applies, issues your invoice and processes refunds. Which Paddle company you buy from depends on where you live. Paddle's buyer terms name it, and they apply to the purchase. We deliver the software and support it.
What each product is
All three are the same HealthSave Observatory software, licensed or run in different ways.
Observatory Care: $99 a year or $9 a month
A licence for the Care features of the Observatory software on your own server, plus email support for that software. Care adds scheduled encrypted backups to off-site storage you control, a restore drill that checks a backup restores, and updates you can roll back. You get a signed licence file and activate it once on your server, which fetches the file from us that one time. After that it works offline and never contacts us. Your health data stays on your server, and Care sends none of it to us.
Observatory Hosted: $19 a month or $190 a year
The same software run as a service: one private Observatory instance per customer, kept updated and backed up. You choose where it runs: on servers we rent in the EU, or in your own cloud account. Hosted is a pre-order today, under the pre-order rules. On servers we run, your health data is on our servers, so we publish Hosted's own privacy notice and data processing terms before we create any instance.
Teams: $99 a month per coach, $499 a month per clinic or lab
One Observatory instance for one organisation, which we install and configure as onboarding, plus email support for the software. Each Teams customer signs a data processing agreement with us before we install anything.
None of these is a medical service or a medical device. The software organises your records and shows your values and trends. It does not diagnose, treat or interpret anything.
The app is a separate purchase
HealthSave for iPhone is sold on the App Store. HealthSave Pro is a one-time in-app purchase under Apple's terms, and Apple handles its billing and refunds. The app will never have a subscription. Nothing you buy here unlocks app features, and Pro does not include Care, Hosted or Teams.
Prices, tax and renewal
- Prices are in US dollars. Paddle shows any sales tax or VAT before you pay.
- Monthly and yearly plans renew at the end of each period until you cancel. Paddle emails a receipt for every charge.
- If we change a price, we email you at least 30 days before the new price reaches your renewal, so you can cancel first.
Cancelling
Cancel any time, from the link in any Paddle receipt or by writing to support@healthsave.app. The plan stays active until the end of the period you paid for and does not renew. We don't refund the unused part of a period; the refund policy lists the exceptions.
- Care. Your Observatory keeps working as the free Community edition. The licence file stays valid for 14 days past its end date, then the Care features stop. Backups you already made stay yours.
- Hosted. We keep your instance for 30 days after the plan ends so you can export it, then delete the instance and its backups.
- Teams. The instance is installed in your own cloud account or on your server, so it stays with you. The licence stops at the end of the paid period, and our maintenance access ends with it.
The source code licence
Observatory's core is source-available under the Elastic License 2.0, and its protocol and SDK layers are under Apache-2.0. Buying Care, Hosted or Teams doesn't change either licence. The free Community edition keeps every feature it has today. A Care licence file unlocks the Care features, and the Elastic License 2.0 does not allow removing or getting around licence checks.
Support
Write to support@healthsave.app. Email from Care, Hosted and Teams customers goes to the front of the queue. One person maintains HealthSave, so there is no phone line and no promised response time.
What we are responsible for
We fix the bugs we can reproduce and ship updates. We can't promise the software never fails, so keep more than one copy of data you care about. Where the law allows, our total liability for any claim is limited to what you paid us in the 12 months before it. Nothing in these terms takes away rights you have under the consumer law where you live.
Changes to these terms
We post every change here with its date. If a change affects a plan you already pay for, we email you before it applies.
