terms and conditions

1. The Service

In short: Aevum runs on your own machine. Accounts, licensing, and cloud AI are the parts that reach our servers.

Aevum is a local-first writing application. Your manuscripts, notes, and related project files are created and stored on your own device. Certain optional features - account sign-in, license entitlements, and cloud AI assistance - connect to our servers at api.aevumwriter.com.

We offer the Service in tiers (currently "Room" (free), "Reader", and "Observatory"). Features available in each tier are described at aevumwriter.com/pricing and may change over time. We may add, modify, or discontinue features of any tier, provided that paid subscribers retain materially equivalent functionality for the remainder of their paid period.

2. Eligibility and Accounts

In short: you must be 16 or older, and your account is yours to look after.

You must be at least 16 years old (or the age of digital consent in your jurisdiction, if higher) to create an account.

You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. Notify us promptly at [email protected] of any unauthorized use. You must provide accurate account information and keep it current.

3. Subscriptions, Billing, and Refunds

In short: subscriptions renew until you cancel, and fees are not refundable except where the law says otherwise.

Paid tiers are sold as subscriptions through our website via our third-party payment processors, Razorpay or Stripe, depending on your region. We do not receive or store your full payment card details.

Subscriptions renew automatically at the end of each billing period unless cancelled before renewal. You can cancel at any time from your account page; cancellation takes effect at the end of the current billing period, and you retain paid features until then.

Except where required by law, fees are non-refundable, including for partial billing periods, unused time, or unused AI capacity. Where a mandatory statutory withdrawal or refund right applies (for example under EU consumer law), we honour it as required.

We may change subscription prices with at least 30 days' notice; changes apply from your next renewal. If you do not accept a price change, cancel before it takes effect.

4. License to Use the App

In short: one licence, for your own writing. Do not share it or tamper with the checks.

Subject to these Terms and payment of applicable fees, we grant you a personal, non-exclusive, non-transferable, revocable license to install and use the Aevum application on devices you own or control, for your own writing work.

You may not:

• share, resell, sublicense, or rent your license or account, or share one license key or account across multiple people;
• circumvent, disable, or tamper with license validation, entitlement checks, usage metering, or other technical protection measures;
• reverse engineer, decompile, or disassemble the application except to the extent such restriction is prohibited by applicable law;
• use the Service to build a competing product, or use automated means to extract the Service's models, prompts, or server behaviour;
• use the Service in violation of applicable law.

Licenses may be bound to a limited number of devices ("machine-bound"). The application includes an offline grace period; after it lapses without server contact, paid features may be suspended until validation succeeds. Free-tier writing functionality is designed to keep working regardless.

We may suspend or terminate access for breach of this Section, including license sharing or tampering with protection measures.

5. Your Content

In short: you own your writing, we do not train on it, and keeping backups is your job.

You own your writing. Manuscripts, notes, world-building material, and anything else you create in Aevum ("User Content") remain yours. We claim no ownership of, and no license to, your User Content except the limited processing described here.

Because Aevum is local-first, your User Content is stored on your device, not on our servers, unless and until you use a feature that transmits it (see Section 6). Where a feature requires transmitting User Content to our servers, you grant us a limited, non-exclusive license to process that content solely to provide the requested feature (for example, to forward it to an AI model and return the response). We do not use your User Content to train AI models, and we do not permit our AI subprocessors to do so under our agreements with them.

You are solely responsible for backing up your User Content. The application stores your work locally; loss of your device, disk failure, or file corruption can result in loss of your work. We are not responsible for lost or corrupted local data.

You represent that your User Content and your use of the Service do not infringe any third party's rights or violate any law.

6. AI Features

In short: three ways to run AI, and checking what it produces is on you.

Aevum offers AI-assisted features in three modes:

• Aevum cloud AI: relevant portions of your manuscript and your prompts are sent to our gateway (api.aevumwriter.com), which forwards them to third-party AI model providers to generate a response. Cloud AI is metered; usage limits per billing window are set and enforced server-side and may change.
• Bring your own key (BYOK): your content is sent directly from your device to the AI provider you configure, under your account and their terms. We are not a party to that relationship and have no responsibility for that provider's handling of your data, its costs, or its output.
• Local models: inference runs on your own device; no content leaves it.

AI output is generated by statistical models and may be inaccurate, incomplete, biased, or similar to content generated for others. You are responsible for reviewing AI output before relying on or publishing it. To the extent we hold any rights in AI output generated for you through the Service, we assign them to you; however, we make no warranty that AI output is original, non-infringing, or protectable by copyright, and you are responsible for how you use it.

You must not use AI features to generate content that is unlawful, or to violate the acceptable-use policies of the underlying model providers.

7. Acceptable Use

In short: do not attack, probe, or abuse the Service.

You agree not to: interfere with or disrupt the Service or its servers; probe, scan, or test the vulnerability of the Service without written authorization; access another user's account or data; use the Service to send spam or malicious code; or misrepresent your affiliation with us.

8. Third-Party Services

In short: the services Aevum connects to have their own terms, and those are between you and them.

The Service interoperates with third-party services (payment processors, AI model providers, and any provider you configure via BYOK or local model tooling such as Ollama). Their services are governed by their own terms and privacy policies. We are not responsible for third-party services.

9. Intellectual Property

In short: the application is ours; everything you write in it is yours.

The Aevum application, website, branding, and all associated software and content (excluding your User Content) are owned by us or our licensors and are protected by intellectual-property laws. Except for the license in Section 4, no rights are granted to you.

If you believe content available through the Service infringes your copyright, contact us at [email protected] with sufficient detail to assess the claim.

10. Feedback

In short: ideas you send us, we may use without owing you anything.

If you send us feedback or suggestions, you grant us a perpetual, irrevocable, royalty-free license to use them without obligation to you.

11. Disclaimer of Warranties

In short: the Service is provided as is, with no guarantees - including about AI output and local data.

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, AND UNINTERRUPTED OR ERROR-FREE OPERATION. WE DO NOT WARRANT THAT AI OUTPUT WILL BE ACCURATE OR SUITABLE FOR ANY PURPOSE, OR THAT LOCAL DATA WILL NOT BE LOST. SOME JURISDICTIONS DO NOT ALLOW EXCLUSION OF IMPLIED WARRANTIES; IN THAT CASE THE ABOVE APPLIES TO THE MAXIMUM EXTENT PERMITTED.

12. Limitation of Liability

In short: what we can be made to pay is capped, and some liability cannot be excluded at all.

TO THE MAXIMUM EXTENT PERMITTED BY LAW: (a) WE ARE NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST DATA (INCLUDING LOST MANUSCRIPTS), OR LOSS OF GOODWILL, ARISING FROM OR RELATED TO THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY; AND (b) OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING FROM OR RELATED TO THE SERVICE IS LIMITED TO THE GREATER OF (i) THE AMOUNTS YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM AROSE AND (ii) USD 50.

Nothing in these Terms excludes liability that cannot be excluded by law, including for death or personal injury caused by negligence, fraud, or, for consumers in certain jurisdictions, statutory consumer guarantees.

13. Indemnification

In short: if your use of Aevum causes a claim against us, it lands with you.

You will indemnify and hold us harmless from claims, damages, and reasonable costs (including legal fees) arising from your User Content, your use of the Service in breach of these Terms, or your violation of law or third-party rights.

14. Termination

In short: either side can end this, and your manuscripts stay on your device either way.

You may stop using the Service and delete your account at any time. We may suspend or terminate your access if you materially breach these Terms (including Section 4), with notice where practicable. On termination, your license under Section 4 ends; Sections 5 (ownership), 9, and 11–17 survive. Because your User Content is stored locally, termination of your account does not delete your manuscripts from your device.

If we terminate a paid subscription without cause, we will refund the pro-rata unused portion of prepaid fees; this is your exclusive remedy for such termination.

15. Changes to the Service or Terms

In short: material changes come with at least 14 days' notice.

We may update these Terms. For material changes we will give notice (in-app, by email, or on the website) at least 14 days before they take effect. Continued use after the effective date constitutes acceptance. If you do not agree, stop using the Service and, if applicable, cancel your subscription.

16. Governing Law and Disputes

In short: Indian law, and the courts at Jalgaon.

These Terms are governed by the laws of India, excluding its conflict-of-laws rules. Courts located in Jalgaon, Maharashtra have exclusive jurisdiction, except that either party may seek injunctive relief in any competent court, and consumers retain any mandatory forum rights under local law.

17. General

In short: the usual clauses about this agreement as a whole.

These Terms, together with the Privacy Policy, are the entire agreement between you and us regarding the Service. If any provision is held unenforceable, the remainder stays in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms; we may assign them in connection with a merger, acquisition, or sale of assets.

18. Contact

In short: how to reach a person about any of this.
