Privacy Policy

Please read these terms and conditions carefully before using our service.

1. Introduction

This Privacy Policy describes how your data is (or more accurately, is not) collected, used, and protected when you use the sWarden platform — a browser-based, encrypted, and anonymous secret manager for storing passphrases, notes, and card information.

We are committed to privacy by design. This means:

  • We do not collect personally identifiable information (PII)
  • We do not track users
  • We do not access your secrets — only you can

By using this platform, you agree to the practices outlined below.

2. Information We Do Not Collect

We designed sWarden to avoid collecting or storing any personal identifiers. Specifically, we do not collect:

  • Names
  • Email addresses
  • Phone numbers
  • IP addresses
  • Device identifiers
  • Location data
  • Behavioral or profiling data

We do not use:

  • Advertising or analytics scripts
  • Browser fingerprinting
  • Third-party cookies
  • Session replays or keystroke trackers

3. Information We Collect

The platform is intentionally designed to minimize data collection. The only information processed is strictly necessary to provide core functionality:

  • 12-words recovery list and user passphrase are never sent to the server. They remain solely on your device and are essential for encryption/decryption
  • Stored secrets (passphrases, notes, cards) are encrypted client-side (in your browser) or at rest using a private key derived from your passphrase
  • Encrypted vault data may be stored server-side, but never in plain text.
  • No admin, developer, or third party can view, decrypt, or access your secrets.

In short: you are the only person who can decrypt your data.

4. Use of Information

All information handled by the platform is used only to provide core service functionality. Specifically:

  • We do not analyze or inspect your secrets
  • We do not monetize any data
  • We do not share any data with third parties
  • We do not require identity or contact information, even for paid accounts
  • No marketing, profiling, or targeted messaging is performed

5. Cookies and Tracking

We do not use tracking technologies. Specifically:

  • No third-party cookies
  • No marketing or retargeting scripts
  • No fingerprinting or behavioral analytics

The platform may use strictly necessary first-party session cookies to maintain anonymous login sessions. These cookies do not store sensitive data and are not used to identify you.

6. Data Security

We take data protection seriously. Our security model includes:

  • Encryption at rest: Encrypted vaults are stored using a private key derived from your passphrase and never exposed in plain text
  • Client-side encryption: Your secrets are encrypted before ever leaving your device
  • Zero-knowledge design: We cannot access, view, or reset your data — ever
  • Quarterly black-box audits: Independent testers conduct regular vulnerability assessments
  • A public [Security Report](#) is available for transparency

There is no plaintext backup or access to your secrets by any system component, administrator, or contributor.

7. User Control and Access

  1. Users are in full control of their secrets, vaults, and recovery credentials
  2. Accounts are created anonymously using a 12-words recovery list and passphrase. If both are lost, the account cannot be recovered
  3. Secrets can be deleted at any time via your profile.
  4. Sharing secrets via temporary links is user-controlled and time-limited.

8. Data Sharing and Disclosure

  1. We do not sell, rent, or disclose your data to any third party
  2. There is no access to your secrets, even by administrators
  3. Any content obtained from the Service

We will not share user's secrets with governments or law enforcement except when legally compelled by a valid court order, and even then, we may be unable to comply due to encryption and anonymity.

9. Children’s Privacy

sWarden is not designed for or directed to children under the age of 16. We do not collect age information since it's an anonymous-first system, but every user must confirm being 16 or older when creating an account.

10. International Data Transfers

sWarden is operated and maintained in Brazil.

By using this service, you consent to the processing and storage of encrypted data in the jurisdictions where we operate servers.

All data remains encrypted and anonymous regardless of geographic storage location.

12. Changes to This Policy

We may update this Privacy Policy from time to time. When we do:

  • Changes will be published in the [changelog](#) and/or visible via a banner on the site.
  • We recommend users review this policy periodically.

Your continued use of the platform signifies your acceptance of the updated terms.

14. Contact

Due to our anonymous-first model, we do not offer email-based support.
