Terms of Service

1. Who we are

These Terms of Service govern your use of Nemosine.

Nemosine is operated by Nemosine AS (organisation number 937 091 567).

• Contact email: support@nemosine.app
• Postal address: Vestre Furmyrveg 26, 6017 Aalesund, Norway

2. Acceptance of these terms

By creating a Nemosine account, enabling cloud sync, buying a subscription, or otherwise using a paid or account-based part of the service, you agree to these Terms.

If you do not agree, do not use account-based or paid features. Local-only use without an account may still be available.

These Terms apply together with the Privacy Policy.

3. Eligibility

You must be at least 16 years old to create a Nemosine cloud account or use Cloud AI. This applies in every country, including where local law sets a lower age.

If you are under 18, you may only purchase a paid subscription with the involvement or permission of a parent or legal guardian, to the extent required by applicable law.

4. The service

Nemosine is a local-first notes product. Features may include:

• local note-taking and organisation
• optional cloud sync
• optional on-device and Cloud AI features
• paid subscription plans
• exports and other related productivity features

Features may differ by device, region, platform, release stage, and subscription tier.

5. Accounts

You are responsible for:

• providing accurate account information
• keeping your login credentials secure
• using a lawful email address you control
• all activity that occurs under your account, unless caused by our own fault

You must promptly notify us at support@nemosine.app if you believe your account has been compromised.

6. Cloud sync and encryption

Cloud sync is optional.

If you enable cloud sync:

• note content and synced media are encrypted on your device before upload
• your login password is separate from your sync encryption password
• some metadata remains visible to the server so authentication and sync can work

That metadata may include account identifiers, randomly generated device identifiers used by the sync algorithm, row or table identifiers, timestamps, versions, deletion markers, and storage or traffic usage counters.

Technical error data is only sent if you choose to submit an error report, and those reports do not include note contents or synced note bodies.

You are responsible for keeping your sync encryption password safe. If you lose it, we may be unable to recover your encrypted synced content.

7. Subscriptions, billing, and pricing

Nemosine may offer free and paid plans.

Pricing may vary by:

• platform
• country or region
• currency
• taxes
• promotional campaigns

The price, billing period, renewal terms, and included features shown at checkout or in the applicable app store purchase flow control that purchase.

Web subscriptions

Web subscriptions are processed through Stripe or another checkout flow we designate. Unless stated otherwise in the purchase flow, subscriptions may renew automatically until canceled.

Apple and Google subscriptions

Subscriptions bought through Apple App Store or Google Play are billed and managed by Apple or Google under their platform terms, billing rules, and cancellation tools.

Cancellation and refunds

Refund requests are handled as described in our Refund Policy.

Mandatory consumer rights under applicable law are not limited by these Terms.

Price changes

We may change prices for future subscription periods or new purchases. Where applicable law requires notice, we will provide notice before the changed price takes effect.

8. User content

You keep ownership of the content you create in Nemosine.

You give Nemosine a limited, non-exclusive right to host, store, transmit, back up, display, and process your content only as needed to operate, secure, improve, and support the service for you.

You are responsible for making sure you have the rights to store and sync the content you upload and that your use of the service is lawful.

9. Acceptable use

You may not:

• use Nemosine for unlawful, fraudulent, or abusive activity
• try to gain unauthorized access to the service or other users' accounts
• interfere with the service, security controls, or infrastructure
• scrape, copy, resell, reverse engineer, or exploit the service except where mandatory law permits it
• upload content that infringes third-party rights
• use the service to distribute malware or harmful code
• bypass or attempt to defeat AI safety controls, rate limits, credit limits, or access restrictions
• use Cloud AI for phishing, deceptive impersonation, unlawful surveillance, doxing, sexual exploitation of children, development of weapons, or other activity prohibited by the selected model provider's applicable-use rules
• use Cloud AI output as the basis for an automated high-impact decision about another person in areas such as employment, housing, credit, insurance, healthcare, or legal services without appropriate qualified human review and any safeguards required by law
• use Cloud AI to train or develop a competing model, or systematically extract or resell model output as a standalone service

We may suspend or restrict access if we reasonably believe your use breaches these Terms, threatens security, or creates legal risk.

When using Cloud AI, you must also comply with the selected provider's current rules: the OpenAI Usage Policies for Luna (Cloud), the xAI Acceptable Use Policy for Grok (Cloud), or the NEAR AI Acceptable Use Policy for GLM 5.3 Flash (NEAR AI). If a provider rule conflicts with mandatory law or these Terms, the stricter lawful restriction applies to your Cloud AI use.

10. AI features and third-party models

Nemosine may offer optional AI features that run on your device or on third-party cloud infrastructure.

On-device AI

Local chat uses Gemma 4, developed by Google DeepMind. Local search and retrieval use Granite Embedding 311M Multilingual R2, developed by IBM.

• Gemma 4 is made available under the Apache License 2.0.
• Granite Embedding 311M Multilingual R2 is made available under the Apache License 2.0. Nemosine uses the LiteRT conversion published by the LiteRT Community.

The complete Apache 2.0 license and model attributions are available in Nemosine under Settings → Legal information → AI model notices.

Optional Cloud AI

Nemosine Pro may offer Luna (Cloud), operated by OpenAI; Grok (Cloud), operated by xAI; and GLM 5.3 Flash (NEAR AI), operated by NEAR AI (Jasnah, Inc.). Cloud AI is optional and does not run until you accept the current Cloud AI Data Processing document. A request may contain your prompt, relevant chat history, included notes or images, tool descriptions, tool calls, and tool results. It is sent only to the provider of the model you selected.

Nemosine sends each provider's requests through an organisational API credential and does not put your Nemosine account identifiers or client IP address in the provider request. For Grok, Nemosine may send an opaque, pseudonymous per-conversation cache-routing value to improve cache reuse. This value is not anonymous: xAI can recognise requests carrying the same value, and request content may identify you or someone else.

Grok is enabled only when our xAI team has Zero Data Retention and our server verifies xAI's ZDR response header. GLM 5.3 Flash runs on NEAR AI's own hardware inside a Trusted Execution Environment, and NEAR AI's terms state it will not use customer data to train generative AI models; Nemosine's relay still handles the request in readable form before forwarding it. For Luna, we ask OpenAI not to store the response as hosted application state, but OpenAI may retain content for abuse monitoring for up to 30 days unless our OpenAI organisation is separately approved and configured for ZDR. We do not opt in to model training with Cloud AI content. See Cloud AI data processing and the Privacy Policy for complete details and withdrawal instructions.

Cloud AI use is measured in tokens and charged against a monthly credit allowance. Different models may consume credits at substantially different rates, as shown in the app. Allowances do not roll over. Per-request, daily, and concurrency limits may apply. Provider availability, model behaviour, prices, limits, and supported models may change; we do not guarantee that a particular cloud model will always be available.

The acceptable-use rules in section 9 apply to all AI features.

AI-generated output may be inaccurate, incomplete, or unsuitable for your intended purpose. You are responsible for reviewing output before relying on, sharing, or acting on it. Nemosine's AI features are not a substitute for professional medical, legal, financial, or other regulated advice.

11. Service availability, beta features, and changes

We work to keep Nemosine available and reliable, but we do not promise uninterrupted or error-free operation.

We may:

• add, remove, or modify features
• set or change storage or usage limits
• perform maintenance
• release beta, preview, or experimental features with reduced support or stability

We may change or discontinue features where reasonably necessary for technical, legal, commercial, or security reasons.

12. Inactivity, suspension, and termination

You may stop using the service at any time.

We may suspend or terminate your access if:

• you materially breach these Terms
• payment is overdue or reversed
• we are required to do so by law
• doing so is reasonably necessary to protect the service, users, or Nemosine

We may delete cloud account data if the account has been inactive for 2 years. Local data stored on your own devices is not automatically removed by server-side account deletion.

Where reasonably practical, we may give notice before deletion or termination, but we may act immediately where security, fraud, abuse, or law requires it.

13. Consumer rights

Nothing in these Terms excludes or limits rights you have under mandatory consumer law.

If you are a consumer, statutory rights that cannot legally be waived remain in force even if any other part of these Terms says otherwise.

14. Disclaimers and limitation of liability

To the maximum extent permitted by law:

• the service is provided on an "as is" and "as available" basis
• we disclaim implied warranties not required by law
• we are not liable for indirect, incidental, special, consequential, or punitive damages

Our total liability arising out of or related to the service is limited to the greater of:

• the total amount you paid to Nemosine for the service in the 12 months before the event giving rise to the claim, or
• NOK 1,000

This limitation does not apply to liability that cannot be limited by law, including liability for wilful misconduct, gross negligence, death, personal injury, fraud, or mandatory consumer rights.

15. Governing law and disputes

These Terms are governed by Norwegian law.

Any dispute that cannot be resolved amicably shall be brought before the ordinary courts of Norway, with Møre og Romsdal District Court as the agreed legal venue, unless mandatory consumer law gives you the right to bring a claim elsewhere.

16. Changes to these Terms

We may update these Terms from time to time.

If we make a material change, we will tell you in the app, summarise what changed on our legal updates page, and ask you to accept the updated Terms before you continue to use account-based features such as cloud sync. Until you accept, cloud sync stays paused. Notes stored on your devices are not affected.

If you do not accept a material change, you can keep using Nemosine on your device without cloud sync, or delete your cloud account in the app and stop using account-based features.

Other changes, such as corrections and clarifications, take effect when we publish them. The date at the top of this page shows when these Terms last changed.
