This Privacy Policy explains how Paperblock collects, uses, shares, and protects personal information when you use paperblock.org and related services (the “Service”).

1) Who we are (Controller)

Paperblock is a community-driven publishing project maintained by volunteers, with operational stewardship provided by Wire Labs Ltda.

Data Controller: Wire Labs Ltda. (“Controller”)
Address: Rodovia Jose Carlos Daux 4150, Florianópolis SC - BR
Privacy contact: [email protected]

2) Personal data we collect

We may collect:

A. Data you provide

  • Email address when you subscribe to newsletters, create an account, sign in via email link, or request updates.
  • Optional details you provide (e.g., name).

B. Data collected automatically

  • Device and usage data such as IP address, browser type, pages viewed, referring URLs, approximate location (derived from IP), and timestamps.
  • Cookies and similar technologies to remember preferences and support sessions/sign-in flows.

C. Communications

  • If you contact us, we receive the content of your message and related metadata.

3) How we use personal data

We use personal data to:

  • deliver newsletters and updates you requested;
  • provide account-related functionality (including authentication via sign-in links, where applicable);
  • operate, secure, maintain, and improve the Service;
  • understand readership and measure performance (analytics);
  • prevent abuse, spam, fraud, and security incidents; and
  • comply with legal obligations and enforce our Terms.

Where the LGPD applies, we may process personal data under one or more legal bases, including:

  • Consent (e.g., newsletter subscription, where required);
  • Legitimate interest (e.g., service security, basic analytics, improving content), with appropriate safeguards;
  • Performance of a contract (e.g., providing account features you request); and/or
  • Legal obligation (e.g., compliance and record-keeping).

5) Sharing and disclosure

We do not sell your personal data.

We may share data with:

  • Service providers that support hosting, email delivery, analytics, security, and operations. They process data under instructions from the Controller and for the purposes described in this Policy.
  • Legal and safety recipients if required by law, regulation, court order, or to protect rights, safety, and integrity of Paperblock, the Controller, contributors, and users.
  • Business transfers if the Service or the Controller undergoes a merger, acquisition, or restructuring (with safeguards as required by law).

6) Cookies and analytics

We use cookies and similar tools to:

  • keep the Service functioning (including session/sign-in features),
  • remember preferences, and
  • understand readership and performance (analytics).

You can control cookies in your browser settings. If you disable cookies, some features may not function properly.

7) Email communications and opt-out

If you subscribe, we will send you emails about new posts or updates. You can unsubscribe anytime using the link in the emails or by contacting [email protected].

Even if you opt out of marketing emails, we may send essential service messages when necessary (e.g., security or account-related notices, if applicable).

8) Data retention

We retain personal data only for as long as necessary for the purposes in this Policy, including legal, accounting, or reporting requirements.

Typical retention examples:

  • Newsletter subscription data: retained until you unsubscribe, and then retained for a limited period where necessary for compliance and suppression lists.
  • Security logs: retained for a limited period appropriate for detecting and preventing abuse and investigating incidents.

9) Security

We apply administrative, technical, and organizational safeguards designed to protect personal data. However, no method of transmission or storage is fully secure.

10) International transfers

Your data may be processed in countries other than where you live (for example, where service providers operate). When required, we adopt appropriate safeguards for international data transfers in accordance with applicable law.

11) Community contributors

Articles may be authored by community contributors. Contributors do not receive access to subscriber lists by default. Subscriber and account data is handled through the Service’s operational systems managed by the Controller and its service providers.

12) Your rights

Depending on your jurisdiction, you may have rights to:

  • confirm whether we process your data and access it;
  • correct incomplete, inaccurate, or outdated data;
  • request anonymization, blocking, or deletion (where applicable);
  • request portability (where applicable);
  • request information about sharing with third parties;
  • revoke consent (where processing is based on consent);
  • object to processing in certain circumstances; and
  • request review of decisions made solely through automated processing, where applicable.

To exercise rights, contact [email protected].

13) Children’s privacy

The Service is not directed to children under 13, and we do not knowingly collect personal data from children under 13. If you believe a child provided personal data, contact us and we will take appropriate steps to delete it.

14) Changes to this Privacy Policy

We may update this Policy from time to time. The “Last updated” date reflects the most recent revision. Continued use of the Service after updates means you acknowledge the updated Policy.
