Terms of Service

Last updated: 3 October 2026

These terms govern your use of Lumineus. By creating an account or using the service you agree to them.

1. The service

Lumineus is a curated, searchable library of public-domain esoteric texts with AI-generated, cited answers drawn from those texts. It is provided for personal study and research.

2. Your account

Provide accurate details, keep your password secure, and don't share your account. You are responsible for activity under your account. One account is for one person.

3. Acceptable use & fair usage

Use the service for your own private study only.
Do not scrape, bulk-download, systematically extract, resell or redistribute the library, its arrangement, or the answers.
Do not attempt to bypass rate limits or access controls, or use automated means beyond normal personal use ("fair usage").

3a. Fair use of Premium

Premium searches and answers are unlimited for normal personal study. That promise covers one person reading, asking and saving at their own pace. It does not cover:

automated or bulk use — scripts, bots, or queries sent in volume by any tool;
reselling access, or passing answers or passages on as part of a service;
sharing an account between several people;
any other use that places an unreasonable burden on the service.

To protect the service, a Premium account meets an automatic ceiling on questions per hour and per day, set far above anything one person reading at their own pace would reach. If you meet it, you are told so at once — and if it was not a mistake, tell us: we would rather raise the ceiling than have it in your way.

If an account's use is far beyond personal study, we may temporarily slow or limit that account, and we will tell the account holder when we do.

4. Intellectual property

The underlying source texts are in the public domain. However, our curation, arrangement, metadata and the synthesised answers are protected — including under the EU sui generis database right — and remain our property. We grant you a personal, non-transferable licence to use them for private study. This does not permit commercial use, redistribution, or re-creation of the database.

4a. Pages you share

You can publish an answer as a shared page at a link anyone can open. You are responsible for what you publish this way — you must have the right to publish it, and it must not be unlawful, infringing, or someone else's private information published without their agreement. This applies to answers built from your own documents in Tabulia as much as to answers from our corpus.

We may remove any shared page, with or without a report and without notice, if we consider it unlawful, harmful, or in breach of these terms. Anyone can report a page using the link on the page itself; reports are read by a person and acted on. Removing a page deletes what it held from the live service — see the privacy policy, which also says how long routine backups keep a copy.

Shared pages expire on their own: 30 days for a free account, 60 days for a paid one, extended by reading only for answers from our corpus. We do not guarantee that a shared page stays reachable for any particular length of time.

5. AI-generated answers

Answers are generated by an AI model from the retrieved public-domain passages. They may contain errors or omissions and are not professional, medical, legal, financial or spiritual advice. Always check answers against the cited sources. Use them at your own discretion.

5a. Tabulia and the AI models it uses

Tabulia, our app for searching your own files, runs AI models on your device. By downloading or using those models you also agree to their terms:

EmbeddingGemma (Google), used for Meaning search. Gemma is provided under and subject to the Gemma Terms of Use found at ai.google.dev/gemma/terms. The copy we distribute has been converted and quantized; it has not been retrained. You must not use it, or let anyone else use it, for anything the Gemma Prohibited Use Policy forbids — among other things: content that infringes anyone's rights; illegal, dangerous or malicious activity, including child sexual abuse material, violent extremism, spam, fraud, phishing or malware; the unlicensed practice of a profession such as law, medicine or finance; harassment, discrimination or the unlawful tracking of people; and misleading others by presenting generated content as human-made. That policy forms part of these terms.
Phi-4-mini-instruct (Microsoft), used to write answers on your device, is licensed under the MIT License.

The full texts are included in the app under Settings → Help → Licences and notices, and are published beside the model files we distribute.

6. Allowances, subscriptions & billing

Without an account, the preview on the front page answers one question a day. A free account includes 3 questions a day — one allowance, shared between this site and the Tabulia app on all your devices. Allowances renew at midnight Central European Time. Premium has no daily allowance, under the fair use above.

Premium is a paid subscription (€8,67 a month or €97 a year), billed through our payment provider acting as merchant of record. You can cancel at any time; access continues to the end of the paid period. We will give notice of any price change.

When a subscription ends, the free account's allowance applies from the following day. In Tabulia, what is over the free limits is locked — never deleted — as the Tabulia terms describe. Copies of your Tabulia filing and saved items that we hold to keep your devices in step are kept for 33 days after the subscription ends and then deleted from our servers.

6a. Messages from us

With an account we send the messages the service needs: about security, changes to these terms, a change that affects your data or access, or a subscription about to end. A newsletter is sent only if you ask for it — the box at sign-up is unticked — and you can stop it at any time with one click on your account page or the link in each newsletter.

7. Availability & changes

We aim for a reliable service but provide it "as is" without guaranteed uptime. We may change, suspend or discontinue features, and may suspend accounts that breach these terms.

8. Liability

To the extent permitted by law, we are not liable for indirect or consequential loss, or for reliance on AI-generated answers. Nothing here limits liability that cannot be limited by law.

9. Governing law

These terms are governed by the law of Denmark. If you use the service as a consumer, this does not take away the protection given to you by the mandatory rules of the country where you live.
