SeferAI ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use SeferAI: the website at seferai.org, the iPhone, iPad and Apple Watch apps, the Android app, and the SeferAI connector for Claude.

Who we are. SeferAI is operated by Health Stream Analytics, LLC, 7724 35th Ave NE, #15897, Seattle, WA 98115, USA, which is the controller of your personal information. SeferAI is not run for profit: subscriptions and support from its users pay for the AI services, voices and servers it runs on, and are what allow it to grow. Health Stream Analytics, LLC is not a registered charity, so support for SeferAI is not tax-deductible.

1. Information We Collect

Information you provide:

• Account Information: When you sign in with Google or Apple, we receive your name and email address; when you sign in with a link sent by email, we receive your email address. Apple Sign-In may provide a private relay email address to protect your privacy. We also keep the account identifier our sign-in provider (Google Firebase) assigns to you.
• Search Queries: The questions and topics you search for within our service.
• Generated Content: Syntheses, study tools and podcast episodes created based on your queries.
• Purchases: If you subscribe, your payment is handled by Apple (App Store), Google (Google Play) or PayPal. We never receive your card or bank details. We keep the subscription record they send us: the plan, its transaction or subscription identifier, its status and its renewal or end date.

On your device only (iPhone and iPad): if you also use our Omer app, SeferAI reads where you are in your Omer count (its start date, or the day you last had open) and the date you last opened Omer, from an area on your device that the two apps share. It uses them to show the day of your count and to remind you to check in. None of this is sent to us. A question that Omer fills in for you is sent only when you tap Ask, like any other search.

Information collected automatically:

• Usage Data: Information about how you interact with our service, including pages visited, features used, and which episodes you play. We record this on our own servers; we do not use third-party analytics services, and our apps contain no analytics or crash-reporting libraries. Separately, Apple and Google may share crash reports and basic app diagnostics with us if you allow this in your device's privacy settings.
• Device Information: Browser type, operating system, and device identifiers.
• Approximate Location: When you first use SeferAI we derive an approximate location (country, region and city) from your connection's internet address, to understand where SeferAI is used. We keep the approximate location, not the address itself. This applies whether or not you have an account.

2. How We Use Your Information

We use the information we collect to:

• Answer your questions and create the syntheses, study tools and podcasts you ask for
• Save your history and episodes to your account and sync them across your devices
• Provide and manage subscriptions
• Send service emails, such as sign-in links and notices that a podcast is ready
• Respond to your questions and support requests
• Count how SeferAI is used (for example how many people use it and from which countries) so we can improve it
• Keep the service secure and prevent abuse

We do not use your information for advertising, and we do not sell it.

3. Information Sharing

We do not sell your personal information, and we do not share it for advertising. We share information only in these cases:

• Service Providers: We use the following services to operate SeferAI. Each receives only the information it needs to perform its function:
  • Anthropic (Claude) - writes syntheses and study tools from your question and the sources found for it
  • Google - sign-in and data storage (Firebase/Firestore), and podcast voices
  • ElevenLabs - premium podcast voices (the text of the episode)
  • Apple, Google Play and PayPal - payments for subscriptions
  • Brevo - sign-in and service emails (your email address)
  • Hetzner - our servers in Germany, which run the service and store audio files
• Public Content: If you choose to make a podcast episode or synthesis public, it will be accessible to anyone via our public pages and feed. If you make it private again, we remove it from our public pages and feed promptly, but we cannot control copies that search engines or others have already made.
• Legal Requirements: We may disclose information if required by law or to protect our rights and safety.
• Business Transfers: If SeferAI or Health Stream Analytics, LLC is involved in a merger, acquisition or transfer of assets, your information may be transferred as part of it. We will tell you by email and/or a prominent notice in SeferAI before your information becomes subject to a different privacy policy.

No training on your content. We do not use your questions, answers or episodes to train AI models, and our AI providers may not either: Anthropic's commercial terms prohibit training on the content we send, Google does not use content sent through its paid API services to improve its products, and we have opted out of ElevenLabs' use of our content for model training. These providers process what we send only to produce the result we requested.

4. How Long We Keep Information

• Accounts: Your profile, history, episodes and subscription records are kept until you delete your account. Deleting it removes them permanently.
• Without an account: If you use SeferAI without signing in, what you create and your approximate location are deleted after 12 months without activity.
• Usage events: Records of individual actions are deleted after 12 months. We keep only totals (for example, the number of users per month and per country), which do not identify anyone.
• Server logs: Our web server logs, which contain internet addresses, are deleted after 14 days.
• Payments: Apple, Google Play and PayPal keep their own payment records under their own policies and legal obligations.

5. Data Storage and Security

Your data is stored securely using industry-standard practices:

• Account and synthesis data is stored in Google Firebase/Firestore
• Audio files are stored on our servers in Germany (Hetzner)
• All data transmission uses HTTPS encryption
• We implement access controls to limit who can access your data

If a security breach compromises your personal information, we will notify you promptly, as applicable law requires.

6. Your Rights and Choices

Wherever you live, you can:

• Access: View the data we have about you in your account, or ask us for a copy
• Correct: Ask us to correct information that is wrong
• Delete: Delete your account and all associated data in the app (Settings → Delete Account) or on the website at seferai.org/delete-account, or contact us at the email below. Deleting your account does not cancel a subscription with Apple, Google Play or PayPal; cancel it there.
• Export: Download your episodes and transcripts, and print or share individual syntheses; for a complete copy of your data, email us
• Opt-out: Choose not to make content public

To exercise a right that is not available in the app, email us from the address on your account so we can confirm it is you. We answer within 30 days.

7. Regional Rights

European Economic Area, United Kingdom and Switzerland

We process your information on these legal bases:

• Contract: to provide the service you use and the subscription you take out - answering questions, saving your history, producing podcasts, managing your account and subscription, and sending sign-in and service emails.
• Legitimate interests: to count usage (including approximate location derived from your internet address), to improve SeferAI, and to keep it secure and prevent abuse. You may object to this processing.
• Legal obligation: where the law requires us to keep or disclose information.

You also have the rights to restrict processing and to data portability, and you have the right to lodge a complaint with the data protection authority in the country where you live or work.

Your information is processed in the United States and in Germany. Where our service providers process personal information from the EEA, the UK or Switzerland in the United States, the transfer is protected by the European Commission's Standard Contractual Clauses (and the UK and Swiss equivalents) or by the provider's certification under the EU-U.S. Data Privacy Framework, as applicable.

California

In the past 12 months we have collected these categories of personal information: identifiers (name, email address, account identifier), commercial information (subscription records), internet or other electronic network activity (usage of SeferAI), approximate geolocation, and the content you create. We collect them from you, from your device, and from the sign-in and payment providers you use, for the purposes in Section 2. We do not sell or share personal information for cross-context behavioral advertising, and we do not use sensitive personal information to infer characteristics about you. Because we do not track you across other sites or sell your data, there is nothing for a Do Not Track or Global Privacy Control signal to switch off, and SeferAI behaves the same whether or not your browser sends one. You have the right to know what we collect, to delete it, and to correct it, and we will not treat you differently for exercising these rights. To make a request, email us as described in Section 6.

8. Cookies and Tracking

We use essential browser storage (cookies or similar local storage in your browser or device) to:

• Keep you signed in to your account
• Remember your preferences (language, synthesis mode)
• Ensure the security of our service

We do not use advertising, third-party tracking cookies, or third-party analytics, and we do not track you across other companies' apps or websites.

9. Children's Privacy

SeferAI is not directed at children under 13, or under 16 where the law of the country they live in sets a higher age for consent to online services. We do not knowingly collect personal information from children under that age. If you believe we have collected such information, please contact us and we will delete it.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes by posting the new policy on this page and updating the "Effective Date."
