1. About this policy
This Privacy Policy explains what Compendium ("we," "us") collects about you, why we collect it, and what choices you have. This policy applies to your use of Compendium on the web, iOS, and Android (the "Service").
2. What we collect
Information you give us:
- Account: email address, authentication information, and full name (optional).
- Library and account activity: books you save, account status, and basic account activity such as sign-in and first-listen timestamps, so we can provide your library and secure your account.
- Billing: subscription and payment-related information needed to provide paid access.
- Support correspondence: emails you send us and the information needed to resolve your request.
Information collected automatically:
- Listening activity: progress and activity needed to resume playback, provide your library, improve the Service, and keep it reliable.
- Technical information: information your browser and device provide when you use the Service, used for reliability, security, and abuse prevention.
- Product analytics: a record of key steps in your use of the Service (for example creating an account, playing or finishing a chapter, reaching the paywall, starting checkout, and subscribing), tied to your account's internal ID rather than your name or email, plus how you first found us (the campaign tags on the link you followed, the referring website's address, and the first page you visited). We use this to understand which parts of the Service work and where people come from. It is sent from our servers to an analytics provider that processes it on our behalf. We don't use it for advertising and don't sell or share it for cross-context behavioral advertising.
3. How we use what we collect
We use your information to (a) provide the Service (stream the right chapter to the right person), (b) provide paid access and customer support, (c) communicate about your account, (d) keep the Service secure and reliable, (e) understand and improve how the Service is used and found, and (f) comply with legal obligations (tax records, lawful requests).
4. Cookies and similar technologies
Compendium uses essential cookies and browser storage to authenticate you, preserve preferences, and operate security controls. Necessary cookies may also be set during authentication and payment flows. We also keep a small record in your browser's storage, for up to 30 days, of how you first arrived (campaign tags, referring website and first page) so it can be attached to your account if you sign up. We don't use analytics or advertising cookies.
5. How long we keep your data
We keep personal information only as long as reasonably necessary to provide the Service, meet legal obligations, resolve disputes, and maintain security. We may retain limited information where needed for these purposes.
6. Your rights
You can:
- Access the data we hold about you — email support@compendium.audio and we will respond as required by applicable law.
- Correct your name or email from your account page.
- Delete your account by emailing us from the address associated with it. Cancel any active subscription first to prevent future renewal. We will verify the request and act on it subject to applicable law and the retention exceptions in §5.
- Object to a particular use, or restrict processing — email us as above.
- Withdraw consent where we relied on it; doing so doesn't affect prior processing.
- Complain to the privacy regulator or attorney general that has jurisdiction over you.
7. Additional privacy rights
Depending on where you live, you may have additional privacy rights under applicable law. To make a request, email support@compendium.audio; we may verify requests against your account before acting.
8. Children's privacy
Compendium is not intended for children under 13. We do not knowingly collect data from anyone in that age range. If you believe a child has created an account, email support@compendium.audio.
9. How we secure your data
We use reasonable administrative, technical, and organizational safeguards designed to protect personal information. We review these measures as the Service changes.
No system is perfectly secure. If a personal-data breach occurs, we will notify regulators and affected users as required by applicable law.
10. Do Not Track
Compendium has no behavioral-advertising tracking to disable. We don't change our behavior based on Do Not Track signals because there's nothing we'd turn off.
11. Changes to this policy
We may update this policy from time to time; the latest version is always at /privacy. Where required, we will provide notice of material changes.
