1. WHAT INFORMATION DO WE COLLECT?
Personal information you disclose to us
In Short: We collect personal information that you provide to us.
We collect personal information that you voluntarily provide to us when you register on the Services, when you participate in activities on the Services, or otherwise when you contact us.
Personal information provided by you. The personal information that we collect depends on the context of your interactions with us and the Services, the choices you make, and the products and features you use. The personal information we collect may include the following:
Email address
Password (stored as a salted hash; we never see your plaintext password)
Display name
Apple User ID and email (only if you sign in with Apple)
Contact and authentication data
Contact preferences
Idea content. Napkin is a note-taking app organized around digital notecards called "Ideas". The text and links you save into your Ideas are personal information for the purposes of this notice. We treat Idea content as private by default — only you can view it through your authenticated account, except where you explicitly share it. Idea content is processed by certain of our service providers (see Section 4) and, in limited cases, by AI providers (see Section 4b).
Sensitive information. We do not actively process sensitive personal information (such as health data, financial account numbers, government IDs, or biometric identifiers). We ask that you do not include this kind of information in your Ideas. If you do, we cannot identify it as sensitive and therefore cannot apply special-category protections to it.
Payment data. We do not collect or store payment card data ourselves. All paid subscriptions are processed by Apple via the App Store and StoreKit. We receive only the transaction receipt, subscription status, and Apple's anonymized transaction identifier from Apple — never the underlying card details. Apple's privacy notice for App Store data is available at https://www.apple.com/legal/privacy/data/en/app-store/.
Application data. If you use our application, we may also collect:
Mobile Device Access. We may request access or permission to certain features from your mobile device. If you wish to change permissions, you may do so in your device's settings.
Mobile Device Data. We automatically collect device information (mobile device ID, model, manufacturer), operating system, version information, system configuration, device and application identification numbers, hardware model, mobile carrier, and Internet Protocol (IP) address.
Push Notifications. We may request to send you push notifications regarding your account or features of the application. You can opt out in your device's settings.
This information is primarily needed to maintain the security and operation of our application, for troubleshooting, and for our internal analytics and reporting purposes.
All personal information that you provide to us must be true, complete, and accurate, and you must notify us of any changes to such personal information.
Information automatically collected
In Short: Some information — such as your IP address and/or browser and device characteristics — is collected automatically when you use our Services.
We automatically collect certain information when you use the Services, primarily for security, operation, troubleshooting, and internal analytics:
Log and Usage Data. Service-related, diagnostic, usage, and performance information our servers automatically record in log files. This may include IP address, device information, app version, and information about your activity in the Services (e.g. timestamps, features used, and crash dumps).
Device Data. Information about the device you use to access the Services, including IP address (or proxy server), device and application identification numbers, browser type, hardware model, mobile carrier, operating system, and system configuration information.
We do not use third-party analytics SDKs or advertising trackers in the application.
2. HOW DO WE PROCESS YOUR INFORMATION?
In Short: We process your information to provide, improve, and administer our Services, communicate with you, for security and fraud prevention, and to comply with law. We may also process your information for other purposes with your consent.
We process your personal information for the following purposes:
To facilitate account creation and authentication and otherwise manage user accounts.
To deliver and facilitate delivery of the Services to the user, including storing your Ideas and synchronizing them across your devices.
To enable AI-powered features, namely flow curation and semantic search of Ideas (see Section 4b).
To process subscription purchases and entitlements via Apple StoreKit.
To respond to user inquiries and provide customer support.
To send you transactional and operational communications (e.g. account, security, billing).
To send you marketing communications if you have opted in (e.g. our newsletter).
To identify usage trends and improve the Services.
For security, fraud prevention, and to comply with our legal obligations.
3. WHAT LEGAL BASES DO WE RELY ON TO PROCESS YOUR INFORMATION?
In Short: We only process your personal information when we believe it is necessary and we have a valid legal reason (i.e., legal basis) to do so under applicable law, like with your consent, to comply with laws, to provide you with services to enter into or fulfill our contractual obligations, to protect your rights, or to fulfill our legitimate business interests.
If you are located in the EU, EEA, the UK, or Switzerland, this section applies to you.
The General Data Protection Regulation (GDPR), the UK GDPR, and the Swiss Federal Act on Data Protection (revFADP / revDSG) require us to explain the valid legal bases we rely on in order to process your personal information:
Performance of a contract (Art. 6(1)(b) GDPR / Art. 31(1) revFADP). Most account, content storage, and subscription processing is necessary to provide the Services you requested.
Consent (Art. 6(1)(a) GDPR / Art. 31(1) revFADP). For optional processing, such as marketing communications. You can withdraw consent at any time.
Legitimate Interests (Art. 6(1)(f) GDPR / Art. 31(1) revFADP). For improving the Services, security, fraud prevention, and analytics on aggregated usage data, where these interests do not outweigh your interests and fundamental rights.
Legal Obligations (Art. 6(1)(c) GDPR / Art. 31(1) revFADP). For example, to comply with tax, accounting, or law-enforcement obligations.
Vital Interests (Art. 6(1)(d) GDPR). In rare cases involving threats to safety.
If you are located in Canada, this section applies to you.
We may process your information if you have given us specific permission (i.e., express consent) to use your personal information for a specific purpose, or in situations where your permission can be inferred (i.e., implied consent). You can withdraw your consent at any time.
In some exceptional cases, we may be legally permitted under applicable law to process your information without your consent, including for fraud prevention, in business transactions, in connection with employment-related collection, where information is publicly available, or where required by law.
4. WHEN AND WITH WHOM DO WE SHARE YOUR PERSONAL INFORMATION?
In Short: We share information with a limited number of service providers ("processors") that help us operate the Services. We do not sell your personal information.
We use the following service providers. Each is bound by a data processing agreement that requires them to process your data only on our instructions and to apply appropriate technical and organizational security measures.
Provider | Purpose | Categories of data processed | Region |
Supabase, Inc. | Cloud infrastructure: database, authentication, serverless functions, realtime sync. Processes all user data including account information, content, and application logs. | Account information, Idea content, application logs | EU — |
Apple Inc. | Authentication (Sign in with Apple) and payment processing (App Store / StoreKit). Used only if you sign in with Apple or hold an App Store subscription. | Apple User ID, email, transaction receipts, subscription status | US (with EU/Swiss data subject protections per Apple's terms) |
Anthropic, PBC | AI inference for flow curation. | Idea content and support message content (no account-level personal data shared) | US |
Cohere Inc. | Vector embedding generation for semantic search. | Anonymized Idea content (no account-level personal data shared) | US / Canada |
Intercom, Inc. | In-app customer support and messaging. | Email address, display name, support conversation history | US |
Mailchimp (operated by Intuit Mailchimp) | Newsletter and marketing email delivery (only if you have opted in). | Email address | US |
In addition, we may share or transfer your information:
Business Transfers. In connection with, or during negotiations of, any merger, sale of company assets, financing, or acquisition of all or a portion of our business to another company.
Legal Obligations. Where we are required by law or by a binding legal request to disclose information, or where we believe in good faith that disclosure is necessary to protect our rights, your safety or the safety of others, or to investigate fraud or respond to a government request.
We do not sell your personal information, we do not share it for cross-context behavioral advertising, and we do not enable third-party advertising trackers in the Services.
4a. INTERNATIONAL DATA TRANSFERS
The European Union, United Kingdom, and Switzerland regulate transfers of personal data outside their territories. The primary storage of your account data and Idea content takes place inside the European Union (Supabase, Frankfurt). However, certain service providers listed above process data outside the EU/UK/Switzerland.
For each transfer outside the EU, UK, or Switzerland, we rely on at least one of the following lawful transfer mechanisms:
EU–US Data Privacy Framework / UK Extension / Swiss–US Data Privacy Framework for recipients that are self-certified under those frameworks (currently: Apple Inc., Intercom Inc., Mailchimp).
Standard Contractual Clauses (SCCs) as adopted by the European Commission (Decision 2021/914) — supplemented, where applicable, by the UK International Data Transfer Addendum and the Swiss FDPIC's recognition of the SCCs.
Your explicit consent in narrow cases where neither of the above applies and the transfer is necessary to provide a feature you requested.
You can request a copy of the transfer mechanism applicable to a specific provider by contacting [email protected].
4b. AI PROCESSING
We use third-party AI providers (Anthropic and Cohere) to enable two features:
Flow curation. When you use AI-assisted features for organizing or surfacing your Ideas, the relevant Idea content (and, for support inquiries, your support message content) is sent to Anthropic for processing.
Semantic search. To enable similarity-based search across your Ideas, the content of your Ideas is sent to Cohere — in anonymized form, not associated with your account identifier — to generate vector embeddings.
What we want you to understand:
No training on your data. Per the API terms we have with Anthropic and Cohere, your content is not used to train their models. Content is processed only to return a response and is not retained beyond the period necessary for the operation, in line with each provider's standard retention policy.
No personal account identifiers shared with Cohere. Idea content sent to Cohere for embeddings is not labeled with your user account.
You remain in control. If you would prefer not to use AI-assisted features, you can disable them in the application settings; this will stop new content from being sent to AI providers, though it does not retroactively delete content that has already been sent.
5. HOW LONG DO WE KEEP YOUR INFORMATION?
In Short: We keep your information for as long as necessary to fulfill the purposes outlined in this privacy notice unless otherwise required by law.
We will only keep your personal information for as long as it is necessary for the purposes set out in this privacy notice, unless a longer retention period is required or permitted by law (such as tax, accounting, or other legal requirements). No purpose in this notice will require us to keep your personal information for longer than twelve (12) months past the termination of your account.
When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize such information, or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.
6. HOW DO WE KEEP YOUR INFORMATION SAFE?
In Short: We aim to protect your personal information through a system of organizational and technical security measures.
We have implemented appropriate and reasonable technical and organizational security measures designed to protect the security of any personal information we process — including encryption in transit (TLS) and at rest, role-based access controls within Napkin GmbH, and contractual security commitments from each of our service providers. However, despite our safeguards and efforts to secure your information, no electronic transmission over the Internet or information storage technology can be guaranteed to be 100 % secure, so we cannot promise or guarantee that hackers, cybercriminals, or other unauthorized third parties will not be able to defeat our security and improperly collect, access, steal, or modify your information. Although we will do our best to protect your personal information, transmission of personal information to and from our Services is at your own risk.
7. WHAT ARE YOUR PRIVACY RIGHTS?
In Short: Depending on your state of residence in the US or in some regions, such as the European Economic Area (EEA), United Kingdom (UK), Switzerland, and Canada, you have rights that allow you greater access to and control over your personal information.
In some regions (such as the EEA, UK, Switzerland, and Canada), you have certain rights under applicable data protection laws. These may include the right (i) to request access and obtain a copy of your personal information, (ii) to request rectification or erasure, (iii) to restrict the processing of your personal information, (iv) if applicable, to data portability, and (v) not to be subject to automated decision-making. In certain circumstances, you may also have the right to object to the processing of your personal information.
You can make such a request by contacting us using the contact details provided in the section "HOW CAN YOU CONTACT US ABOUT THIS NOTICE?" below.
If you are located in the EEA or UK and you believe we are unlawfully processing your personal information, you also have the right to complain to your Member State data protection authority or UK data protection authority.
If you are located in Switzerland, you may contact the Federal Data Protection and Information Commissioner (FDPIC / EDÖB).
Withdrawing your consent: Where we rely on your consent, you have the right to withdraw it at any time, without affecting the lawfulness of processing before the withdrawal. To do so, contact us using the details below or update your preferences in the application.
Opting out of marketing and promotional communications: You can unsubscribe from our marketing emails at any time by clicking the unsubscribe link in any email we send, or by contacting us. We may still send you service-related messages (e.g. password resets, billing notices) that are necessary for the administration of your account.
Account information. If you would like to review or change information in your account or terminate your account, you can log in to your account settings and update your account, or contact us. Upon your request to terminate your account, we will deactivate or delete your account and information from our active databases. We may retain some information to prevent fraud, troubleshoot problems, assist with investigations, enforce our legal terms and/or comply with applicable legal requirements.
If you have questions or comments about your privacy rights, you may email us at [email protected].
8. CONTROLS FOR DO-NOT-TRACK FEATURES
Most web browsers and some mobile operating systems and mobile applications include a Do-Not-Track ("DNT") feature or setting you can activate to signal your privacy preference not to have data about your online browsing activities monitored and collected. At this stage, no uniform technology standard for recognizing and implementing DNT signals has been finalized. As such, we do not currently respond to DNT browser signals or any other mechanism that automatically communicates your choice not to be tracked online. If a standard for online tracking is adopted that we must follow in the future, we will inform you about that practice in a revised version of this privacy notice.
California law requires us to let you know how we respond to web browser DNT signals. Because there currently is not an industry or legal standard for recognizing or honoring DNT signals, we do not respond to them at this time.
9. DO UNITED STATES RESIDENTS HAVE SPECIFIC PRIVACY RIGHTS?
In Short: If you are a resident of California, Colorado, Connecticut, Delaware, Florida, Indiana, Iowa, Kentucky, Montana, New Hampshire, New Jersey, Oregon, Tennessee, Texas, Utah, or Virginia, you may have the right to request access to and receive details about the personal information we maintain about you and how we have processed it, correct inaccuracies, get a copy of, or delete your personal information. You may also have the right to withdraw your consent to our processing of your personal information. These rights may be limited in some circumstances by applicable law.
