Terms of Service

Last updated: 28 April 2026.

1. The agreement

By installing, signing into, or paying for any Eidolon product, you agree to these terms. Per-product additions (e.g., Eidolon Care's data processing agreement, Eidolon Clinic's clinical-use addendum) sit on top of these baseline terms.

2. The licence

Eidolon products are licensed, not sold. You receive a non-exclusive, non-transferable licence to use the product per your plan:

• Personal (£49 one-time) — for personal, non-commercial use on devices you own.
• Professional (£149 one-time) — adds commercial-use rights and priority support.
• SaaS products — per the seat/tenant terms on each product's pricing page.

3. Your data, your property

You own the data you input into Eidolon products. For local-first products (Personal), the data never reaches us. For SaaS products, we process the data as your processor (UK GDPR Article 28), under your documented instructions.

4. Acceptable use

Don't use Eidolon products to attack, deceive, or harm others; don't use them to circumvent regulation that applies to your context (safeguarding, clinical safety, financial reporting); don't reverse- engineer the binaries to extract our model or licence enforcement.

5. Refunds & guarantees

Personal and Professional ship with a 14-day money-back guarantee. SaaS products are pro-rated on cancellation. We do not offer refunds for usage beyond the guarantee window unless required by consumer protection law (UK CRA, AU ACL).

6. Service availability

SaaS products target 99.5% monthly availability for the institutional plans, 99.0% for individual plans. Local-first products do not depend on our uptime. Planned maintenance is announced 7 days in advance.

7. Liability

To the extent permitted by law, our aggregate liability under these terms is capped at the fees you paid in the 12 months preceding the claim. We are not liable for indirect or consequential losses. Nothing in these terms limits liability for fraud, death, or personal injury caused by negligence, or any liability that cannot be excluded by law.

8. Termination

You can cancel any subscription at any time from your billing dashboard. We can terminate access for material breach (e.g., misuse under §4) with 14 days' written notice. On termination, you can export your data; after a 90-day grace period it is deleted from our systems.

9. Governing law

These terms are governed by the laws of England and Wales. AU users benefit from non-excludable consumer guarantees under the Australian Consumer Law in addition to these terms. Disputes are resolved in the courts of England and Wales unless local consumer protection law mandates a local forum.

10. Updates to these terms

We give 30 days' notice (by email to billing contacts and an in-app banner) before material changes take effect. Continued use after the effective date constitutes acceptance.
