Terms of Use — Sketch Focus

Last updated: May 2026 · Applies to iOS & Android

The short version

Use Sketch Focus to actually focus — not to break things. An optional account lets you sync sessions, unlocks, and sketches across devices. The app, the artwork, and the unlock system are ours; your own focus data is yours. Don't reverse-engineer the app, don't use it to harass anyone, and remember the app blocker is a productivity tool — not a substitute for safety software.

1. Acceptance of Terms

By downloading, installing, or using Sketch Focus, you agree to these Terms of Use. If you do not agree, do not use the app. These terms apply to all versions of Sketch Focus on iOS and Android, including future updates and features.

2. About Sketch Focus

Sketch Focus is a focus timer app developed by Core Tattva, based in Sydney, Australia. You set a duration, optionally block distracting apps, and a hand-drawn sketch progresses stroke by stroke as the session runs. Completed sessions unlock new sketches, themes, and streaks.

3. Account & Login

An account is optional. Sketch Focus runs fully without sign-in. If you choose to create an account, it exists so you can sync your sessions, streaks, unlocked sketches, and preferences across multiple devices. You may sign in with email or supported third-party providers (e.g., Sign in with Apple, Google). You are responsible for keeping your sign-in credentials confidential and for any activity that occurs under your account.

4. Account Eligibility

You must be at least 13 years old (or the digital-consent age in your jurisdiction) to create an account. By creating an account you confirm the information you provide is accurate and that you will keep it current. We may suspend or close accounts that violate these terms or that are used to abuse, impersonate, or harass others.

5. Deleting Your Account

You can delete your account at any time from within the app or by emailing dev@coretattva.com. When you delete your account, your synced session history, streaks, and unlocks are removed from our servers. Local data on your device remains under your control and is removed by uninstalling the app.

6. Pricing & Purchases

The core Sketch Focus experience — timer, live sketch, app blocker, and unlocks — is free to use. If we introduce optional paid features in the future, prices and billing terms will be clearly disclosed in the App Store or Google Play before any charge. All payments are processed by Apple or Google; Core Tattva never receives your card or bank details.

7. Permitted Use

You may use Sketch Focus for your own personal, non-commercial focus and productivity. You agree not to: (a) reverse-engineer, decompile, or extract source code from the app; (b) bypass, tamper with, or attempt to disable the app blocker or unlock system; (c) automate, script, or fake completed sessions to game the reward system; (d) reproduce, resell, or redistribute the sketches, artwork, or app content commercially; or (e) use the app in any way that violates applicable laws.

8. App Blocking Feature

Sketch Focus offers an optional "Block Apps" feature designed to help you stay focused during a session. It is a self-imposed productivity tool — not a parental-control, security, or screen-time enforcement product. You acknowledge that no app blocker is fool-proof, that the operating system ultimately controls which apps run on your device, and that Core Tattva is not liable for distractions, missed notifications, or activity that occurs outside an active session.

iOS

On iOS, the blocker uses Apple's Family Controls and Screen Time framework. Your selected apps are stored as opaque tokens issued by iOS — Sketch Focus cannot see which apps you picked.

Android

On Android, the blocker uses the Usage Access and Display Over Other Apps permissions to detect the foreground app and render the blocking overlay. These permissions are used only during an active session.

9. Intellectual Property

All content within Sketch Focus — the interface, the hand-drawn sketches, the unlock system, themes, artwork, and branding — is owned by Core Tattva or its licensors and protected by applicable intellectual property laws. We grant you a personal, non-exclusive, non-transferable, revocable licence to use the app and its content for personal, non-commercial purposes. You may not copy, redistribute, or create derivative works from the sketches or app content without our written permission.

10. Your Content

You retain ownership of any content you create within the app (e.g., session notes, custom labels). When you use the optional sync feature, you grant Core Tattva a limited licence to store and transmit that content solely to provide the sync service across your devices. We do not sell, license, or use your content for any other purpose.

11. Disclaimer of Warranties

Sketch Focus is provided "as is" without warranties of any kind. Core Tattva makes no warranties, express or implied, that the app will be error-free, uninterrupted, secure, or suitable for any particular purpose. The app blocker, sync service, and unlock system are provided on a best-effort basis and may be affected by operating-system updates, device settings, or network conditions outside our control.

12. Limitation of Liability

To the fullest extent permitted by law, Core Tattva and its developers are not liable for any indirect, incidental, special, or consequential damages arising from your use of, or inability to use, the app — including loss of focus sessions, streaks, unlocks, productivity, or data. Our total liability for any claim shall not exceed the amount you paid us (if any) in the twelve months preceding the claim.

13. Termination

We may suspend or terminate your access to Sketch Focus — including any optional account — if you breach these terms or use the app in a way that harms other users, Core Tattva, or third parties. You may stop using the app at any time by uninstalling it or deleting your account.

14. Governing Law

These Terms of Use are governed by the laws of New South Wales, Australia, without regard to conflict-of-law principles. Any disputes arising from these terms or your use of Sketch Focus shall be subject to the exclusive jurisdiction of the courts of New South Wales, Australia.

15. Changes to These Terms

We may update these terms from time to time. When we do, we will post the revised version here with an updated date. If the changes are material, we will also surface a notice in the app. Continued use of Sketch Focus after changes are posted constitutes your acceptance of the updated terms.
