Privacy Policy.

Effective Date: April 28, 2026  ·  Last Updated: April 28, 2026

This Privacy Policy explains how Oppalin ("Oppalin", "we", "us", or "our") collects, uses, shares, and protects personal data when you use the Oppalin service at oppalin.com (the "Service").

This Policy is written to be readable. We try to say what we actually do, in plain language, with the legal detail that applicable laws require. Where local law gives you stronger rights than this Policy describes, those rights apply.

Quick summary (not a substitute for the rest of this Policy):


1. Who is responsible for your data

The data controller (under GDPR, UK GDPR, and similar laws) and equivalent operator (under LGPD) is:

Fabio Torlai Pereira. Address: Fernando de Noronha 436, Curitiba – PR, Brazil

For privacy questions, contact: privacy@oppalin.com

If you are in the European Economic Area, the United Kingdom, or another jurisdiction that grants you the right to lodge a complaint with a supervisory authority, you can do so. In Brazil, the relevant authority is the Autoridade Nacional de Proteção de Dados (ANPD).


2. What this Policy covers

This Policy applies to personal data we process when you:

It does not cover websites, apps, or services operated by other people, even if you reach them through Boards or links shared on the Service.


3. What personal data we collect

We collect only what we need. Here's the full list, organized by source.

3.1 Information you give us directly

Account information. When you create an Account, our identity provider (Clerk) collects your email address, a password (or a third-party login such as Google), and any optional profile information you choose to provide (such as a display name or avatar). Clerk handles this data on our behalf — see Section 6.

Subscription and billing information. If you subscribe to a paid plan or purchase a Founders' Lifetime License, our payment provider (Stripe) collects your payment details directly. We don't store full payment card numbers on our systems. We do receive and store: a Stripe customer ID, the plan you bought, billing dates, the last four digits of the card and its country, and invoice records.

Content. Anything you upload, draw, write, or otherwise add to a Board: images, text, drawings, arrows, links, and similar items. This is stored on our infrastructure for as long as the Board exists.

Communications. If you email us, fill out a form, or send feedback, we keep a record of the communication and our response.

Waitlist signups. If you join a waitlist (such as the Max-tier waitlist), we collect your email address and the date you signed up.

3.2 Information we collect automatically

Technical and device data. When you use the Service, we receive: IP address, browser type and version, operating system, device type, screen resolution, language preference, referring URL, and timestamps.

Usage data. We log basic events: pages visited, Boards opened, features used, and errors encountered.

Real-time collaboration data. When you have a Board open with others, we transmit cursor position, selection state, presence, and the changes you make to Board Content. This is short-lived sync data — it's not stored beyond what's needed to keep Collaborators in sync and recover from disconnections.

Cookies and similar technologies. We use cookies and similar storage on your device. See Section 9.

3.3 Information from third parties

Identity providers. If you sign in with Google (or another third-party login), we receive the data they share with us — typically your email address, name, and profile picture.

Payment providers. Stripe shares the subscription and transaction information described in Section 3.1.

We do not buy personal data from data brokers, and we don't combine your Service activity with data acquired from outside sources for advertising or profiling.

4.1 What we do not do


5. How Boards and sharing affect privacy

Private Boards are visible only to you and Collaborators you explicitly invite.

Link-shared Boards are visible to anyone with the link. We can't control who that link is forwarded to.

Public Boards are visible to anyone with the URL and may be indexed by search engines.

When other users contribute Content to a Board you own, you'll see their display name and any avatar they've chosen, alongside the Content they've added.


6. Who we share your data with

We share personal data with a small number of providers and parties, only as needed and with appropriate safeguards.

6.1 Service providers ("subprocessors")

ProviderWhat they doWhere they're based
CloudflareHosting, content delivery, edge compute (Workers), database (D1), object storage (R2)Global network, with data centers worldwide
ClerkAuthentication, account management, session handlingUnited States
StripePayment processing, billing, invoicingUnited States, with EU subprocessors

A current list of subprocessors will be maintained at oppalin.com/subprocessors. We'll provide reasonable notice of material changes.

6.2 Other recipients

We may also share personal data with professional advisers (lawyers, accountants, auditors) bound by confidentiality; with authorities where required by law; and in connection with a corporate transaction such as a merger or acquisition.

We do not sell or rent your personal data, and we do not share it for cross-context behavioral advertising.


7. International data transfers

The Service uses providers and infrastructure in multiple countries. Your personal data may be transferred to, stored in, and processed in countries other than the one you live in — including the United States and the European Union.

Where required, we rely on appropriate safeguards including Standard Contractual Clauses (SCCs) and Brazil-recognized transfer mechanisms under the LGPD. You can ask us for a copy at privacy@oppalin.com.


8. How long we keep your data

CategoryRetention
Account dataWhile your Account exists, plus up to 90 days after deletion in backup systems
Board ContentWhile the Board exists; up to 90 days after Board deletion in backup systems
Subscription and billing recordsAt least 5 years after the transaction (Brazilian tax/accounting law)
Communications and support recordsUp to 3 years after the last communication
Real-time collaboration sync dataShort-lived; not retained beyond what's needed to keep Collaborators in sync
Server logs (technical and security)Up to 12 months
Waitlist signupsUntil you ask to be removed, or until the waitlist purpose ends

9. Cookies and similar technologies

Strictly necessary. To run the Service — for example, to keep you signed in (set by Clerk), remember your preferences, and protect against abuse.

Functional. To remember choices you've made, such as your last opened Board or UI preferences.

Analytics. To understand how the Service is used in aggregate, so we can improve it. If we use analytics that require consent in your jurisdiction, we'll ask for it before setting those cookies.

We don't use advertising cookies, and we don't track you across other websites. You can control cookies through your browser settings.


10. Your rights

Whatever jurisdiction applies, you can access, correct, delete, and export the personal data we hold about you. Contact us at privacy@oppalin.com.

10.1 EEA, UK, and Switzerland (GDPR / UK GDPR)

You also have the right to restrict processing, object to processing based on legitimate interest, withdraw consent, not be subject to fully automated decisions, and lodge a complaint with your local supervisory authority.

10.2 Brazil (LGPD)

Under LGPD Article 18 you have additional rights including confirming whether we process your data, receiving information about sharing, anonymizing or blocking unnecessary data, and filing a complaint with the ANPD.

10.3 California (CCPA / CPRA)

California residents may know, delete, correct, and opt out of the sale or sharing of personal information (we do not sell or share it). We won't discriminate against you for exercising these rights.

To exercise any right, email privacy@oppalin.com. We'll respond within the timeframes required by applicable law.


11. Security

We use TLS for traffic in transit, encryption at rest where provided by our infrastructure, access controls, authentication via Clerk, and payment processing isolated to Stripe. No system is perfectly secure. If you suspect unauthorized access, contact security@oppalin.com.


12. Children's privacy

The Service is not intended for children under 13, and we do not knowingly collect personal data from children under 13. If we learn that we've collected such data, we'll delete it. Contact privacy@oppalin.com if you believe a child has given us personal data.


13. Changes to this Policy

We may update this Policy from time to time. For material changes, we'll provide at least 30 days' notice by email or in-app notice. Non-material changes (clarifications, typo fixes, subprocessor list updates) take effect when we update the "Last Updated" date.
