# Terms of Service Source: https://www.nemosine.app/terms Last updated: 2026-11-06 ## 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](mailto: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](/privacy). ## 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](mailto: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. Nemosine keeps a local error log on your device without note contents. The log is only sent if you choose to send feedback and tick the option to attach it. If you allow it, the app also sends short error reports automatically: what went wrong and where in the app's code, never note contents, synced note bodies, chat text or your account. The app asks before it sends any, and you can turn this off in Settings › Send feedback. The Privacy Policy lists what a report contains. You are responsible for keeping your sync encryption password safe. If you lose it, we may be unable to recover your encrypted synced content. Nemosine does not encrypt the notes stored on your device itself, and it does not yet lock the app with Face ID, Touch ID or a passcode. The sensitive-content PIN hides content but does not encrypt it. Your notes on the device are as safe as the device: protect it with a passcode and keep its own encryption turned on. Section 6 of the [Privacy Policy](/privacy) explains these limits. ## 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 Subscriptions bought on the web are sold by **Nemosine AS** and processed through RevenueCat Web Billing, with Stripe as the payment processor. The price shown at checkout includes applicable VAT or sales tax for your country. Unless stated otherwise in the purchase flow, a subscription renews automatically at the end of each billing period until canceled. You can cancel at any time from the subscription management page that Nemosine links to under Manage Pro; cancellation stops the next renewal, and you keep Pro until the end of the period you have paid for. ### 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 Canceling stops future renewals and does not by itself refund a charge already made. For web purchases, we review refund requests sent to [support@nemosine.app](mailto:support@nemosine.app) within 14 days of the charge, and refund accidental duplicate charges, mistaken purchases and paid periods in which a technical problem on our side kept you from using Pro. Refunds go back to the original payment method. Apple and Google decide refunds for purchases made through them. The full rules are in our [Refund Policy](/refund-policy). Mandatory consumer rights under applicable law are not limited by these Terms. ### Right of withdrawal for consumers in the EU and EEA If you are a consumer in the EU or the EEA, including Norway, you may withdraw from a web purchase within **14 days** of the day you made it, without giving a reason. To withdraw, send a clear statement to [support@nemosine.app](mailto:support@nemosine.app) or by post to Nemosine AS, Vestre Furmyrveg 26, 6017 Aalesund, Norway. You may use the form below, but you do not have to. Sending your statement before the 14 days end is enough. Nemosine Pro starts as soon as your purchase completes. By confirming a web purchase you ask us to start providing Pro immediately, during the withdrawal period, and you acknowledge that if you withdraw you pay for the part of the period in which Pro was available to you, in proportion to the full price of that period. If you withdraw, we refund the rest of what you paid to the original payment method within 14 days of receiving your statement. The right of withdrawal does not apply to purchases made through Apple or Google; Apple and Google apply their own rules. **Withdrawal form.** To Nemosine AS, Vestre Furmyrveg 26, 6017 Aalesund, Norway, support@nemosine.app: I hereby give notice that I withdraw from my contract for the following service: Nemosine Pro (monthly / yearly / founder yearly). Ordered on: [date]. Name: [name]. Email used for the purchase: [email]. Date: [date]. ### 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 model provider's current rules: the [OpenAI Usage Policies](https://openai.com/policies/usage-policies/) for Luna (Cloud). 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 **NeoN** and **NeoN Plus**, Nemosine's names for the MiniCPM5 1B and 2B models developed by OpenBMB, and on Mac also **K2 Horizon**, developed by the Institute of Foundation Models (IFM) at MBZUAI. Earlier installs may still run Gemma 4, developed by Google DeepMind. Local search and retrieval on supported Apple devices use EmbeddingGemma 2, developed by Google DeepMind. - [MiniCPM5](https://huggingface.co/openbmb/MiniCPM5-1B), [K2 Horizon](https://huggingface.co/IFM/K2-Horizon-3.7B) and Gemma 4 are made available under the [Apache License 2.0](https://www.apache.org/licenses/LICENSE-2.0). NeoN and NeoN Plus are not OpenBMB products. - [EmbeddingGemma 2](https://huggingface.co/google/embeddinggemma-2) is made available under the Apache License 2.0 and is subject to the [Gemma Prohibited Use Policy](https://ai.google.dev/gemma/prohibited_use_policy). Nemosine runs its own Core ML conversion of the text model. The complete Apache 2.0 license, model attributions and modification notices are available in Nemosine under **Settings → Legal information → AI model notices**. ### Optional Cloud AI Nemosine Pro may offer Luna (Cloud), a GPT-6 model operated by OpenAI. It is the only cloud model. Cloud AI is optional and does not run until you accept the current Cloud AI Data Processing document, which the app asks for once, at your first message to Luna. A request may contain your prompt, relevant chat history, included notes or images, tool descriptions, tool calls, and tool results, and is sent to OpenAI through Nemosine's relay. Nemosine sends requests through an organisational API credential and does not put your Nemosine account identifiers or client IP address in the provider request. Request content may still identify you or someone else. Luna's internal reasoning is returned encrypted by OpenAI, stored on your device with the chat, and sent back with later messages in that chat. Notes you mark sensitive stay out of Cloud AI requests until the app has warned you and you have chosen to include them. 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 Zero Data Retention. We do not opt in to model training with Cloud AI content. See [Cloud AI data processing](/ai-data-processing) and the [Privacy Policy](/privacy) 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](/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. ## 17.
