Terms of Service & Privacy Policy

These terms are an agreement between you and ButterDraw.com (“ButterDraw”, “we”, “us”, “our”), the operator of the butterdraw.com service (the “service”). By using the service you agree to them. You can reach us through the in-app Support & feedback button.

1. Preview / “as-is” service

The service is provided on an “as is” and “as available” basis, without warranties of any kind, whether express or implied — including but not limited to merchantability, fitness for a particular purpose, reliability, availability, accuracy, or non-infringement. We do not promise that the service will be uninterrupted, secure, error-free, or that any data you create will be preserved.

2. Your data and backups

You are responsible for keeping your own copies of anything you value. Diagrams, accounts, shared links, and any stored content may be lost, corrupted, reset, or deleted at any time. Use the export options (JSON, PNG, PDF, Mermaid, HTML) to back up your work. We are not responsible for any loss of data.

3. Limitation of liability

To the maximum extent permitted by law, we accept no responsibility or liability for any problems, damages, losses, or costs of any kind arising from your use of — or inability to use — the service. This includes, without limitation, lost data, lost work, lost profits, business interruption, or any direct, indirect, incidental, special, consequential, or punitive damages, even if we have been advised of the possibility of such damages. You use the service entirely at your own risk.

Nothing in these terms excludes or limits liability that cannot be excluded or limited under applicable law, including the Business Practices and Consumer Protection Act (British Columbia) or liability for fraud or for death or personal injury caused by negligence. Where liability cannot be excluded, our total aggregate liability to you is limited to the amount you paid us for the service in the 12 months before the claim (which, for the free preview, is nil).

4. Acceptable use

Don’t use the service for anything unlawful, abusive, or harmful; don’t try to disrupt, overload, reverse-engineer, or gain unauthorised access to it or to other users’ content; and don’t upload content you don’t have the right to use. We may suspend or remove access at any time, for any reason, without notice.

5. Intellectual property

Your content. You keep ownership of the diagrams and other content you create with the service (“your content”) — we claim no ownership of it. You grant us only the limited permission we need to run the service: to store, back up, transmit, and display your content to you and to the people you choose to share it with, and to make the technical copies (such as caches) required to do that. We use this permission only to operate and improve the service for you; we do not sell your content or use it for advertising. Cloud-saved diagrams are encrypted in your browser before they reach us, so we cannot read their contents (see the Privacy Policy). You are responsible for having the rights to any content you create or upload.

Our content. The service itself — including ButterDraw, the butterdraw.com software and source code, its design and look and feel, and the ButterDraw name and logo — belongs to us or our licensors and is protected by copyright and other laws. ButterDraw is proprietary software and is not open source. We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to use the service for its intended purpose while these terms are in effect; this gives you no ownership of the service. Except where the law says we may not restrict you, you may not copy, modify, distribute, sell, sublicense, or reverse-engineer the service. The service uses third-party open-source components that remain under their own licences; you can view those licences in the app (Help → “Third-party licenses”).

© 2026 ButterDraw. All rights reserved.

6. Changes to these terms

These terms may be updated as the service evolves. If they change in a meaningful way, you’ll be asked to review and accept the updated terms before continuing. Continued use after an update means you accept the revised terms.

7. Governing law

These terms are governed by the laws of the Province of British Columbia, Canada and the federal laws of Canada that apply there, without regard to conflict-of-law rules. You and ButterDraw agree to the exclusive jurisdiction of the courts located in British Columbia, subject to any non-waivable rights you have under the consumer-protection laws of the place where you live.

8. Acceptance

By ticking the box below and continuing, you confirm that you have read, understood, and agree to these Terms of Service and the Privacy Policy below, and that you understand the service is an experimental preview offered without warranty or liability.

Privacy Policy

This policy explains what information ButterDraw collects, why, and your choices.

P1. Telemetry & troubleshooting information

To keep the service working and to diagnose problems — especially while it is in preview, when we rely on this to find and fix issues quickly — we collect diagnostic and usage information, including:

• Error and crash reports — JavaScript errors, failed requests, and related technical details.
• Usage and feature events — e.g. which tools and shapes you use, diagrams created/opened/saved, exports, AI calls, share links, and collaboration joins, plus aggregate per-day counts.
• Performance timings — how long actions such as saving, activation, and AI calls take.
• Interaction diagnostics — a time-ordered stream of pointer, viewport, and selection events used to reconstruct what happened in a session for troubleshooting. We do not record a video of your screen.
• Device/session basics — such as browser type, screen size, and a session identifier.
• Referral / campaign tags — UTM parameters present on a link you followed to reach us.

P2. Account, sign-in & information you provide

Account & sign-in. When you sign in with Google we receive and store your Google account email address, a user identifier, and the times you sign in. We keep this for all signed-in users, including free accounts with no premium code, to operate accounts, prevent abuse, and contact you about the service. Sign-in is handled by Google Firebase Authentication; your use of Google sign-in is also governed by Google’s Privacy Policy.

• Support requests — the message, screenshots, and logs you attach when you contact support.
• Collaboration — the display name you choose, and your verified Google email, when you join a shared diagram.
• Teams — if you own or join a team, we store the team’s membership (including members’ email addresses) so the owner can manage seats and members.
• Premium / Team — the email associated with your account and any code you redeem.
• Policy acceptance — the version of these Terms & Privacy Policy you accept, with the date and a hashed record, kept against your account.
• Your diagrams — content you save to the cloud. It is encrypted in your browser before it reaches us and we cannot read it.

P3. How we use it

We use this information to operate, secure, maintain, debug, and improve the service, to understand which features are used, to respond to support requests, and to prevent abuse. During preview we may collect more diagnostic detail than we expect to keep long term, and we will reduce it as the service matures.

P4. Sharing & storage

Authentication is provided by Google (Firebase Authentication); other data is stored on our cloud infrastructure (Microsoft Azure). We may share data with service providers who host or process it on our behalf, or where required by law. Data may be processed in Canada and other countries.

AI features. When you use an AI feature — Ask AI (Quick Amend), the AI Assistant, AI Import, Ask help, or Whiteboard import (turning a photo of a whiteboard into shapes) — the text you provide (your instruction or question), for the diagram-editing features a summary of your current diagram, and for Whiteboard import the photo you upload, are sent to our AI model provider (via Microsoft Azure AI Foundry) to generate the result. This content is sent in the clear to that provider for that purpose (the end-to-end encryption that protects your saved cloud diagrams does not apply to what you send to an AI feature). We do not retain the photo you upload after the conversion. AI features are optional and only run when you choose to use them.

P5. Retention

Telemetry and session diagnostics are automatically deleted on a rolling basis (by default after about 90 days). Aggregate counts that contain no personal information may be kept longer. Account and sign-in information (email, identifier, timestamps), team rosters, and your policy-acceptance records are kept until you delete your account or ask us to remove them. Content you save is kept until you delete it or your account/diagram is removed.

P6. Your choices

We honour your browser’s Do Not Track / Global Privacy Control signal and stop diagnostic capture when it is set. You can ask us to access or delete your personal information, or ask a privacy question, through the in-app Support & feedback button.

P7. Changes to this policy

We may update this policy as the service evolves; meaningful changes will be surfaced for you to review, as with the terms above.
