Terms of Service

Last updated: March 27, 2026

1. Agreement

By purchasing and using AdErasr, you agree to these terms. If you don't agree, don't use the app. You must be at least 13 years old to use AdErasr.

2. License

AdErasr is licensed, not sold. You receive a non-exclusive, non-transferable license to use the app on Apple devices you own or control, subject to Apple's standard Licensed Application End User License Agreement.

3. What AdErasr Does

AdErasr is a privacy protection app for iOS that blocks ads, trackers, annoyances, and other unwanted content. It operates through three mechanisms:

• Safari Content Blockers — Six content blocker extensions that block network requests and hide elements in Safari using Apple's Content Blocker API. All blocking happens on-device.
• Safari Web Extension — A browser extension that provides cosmetic filtering, cookie consent auto-dismissal, anti-adblock countermeasures, and block counting within Safari.
• Aegis (System-Wide Protection) — An optional URL filter that blocks ad and tracker domains across all apps on your device using Apple's iOS 26 NEURLFilter API. Aegis uses a local Bloom filter and Apple's privacy-preserving PIR (Private Information Retrieval) relay architecture. You must explicitly enable Aegis in the app.

4. Cookie Consent Auto-Dismissal

AdErasr automatically dismisses cookie consent banners by clicking "Reject All" or equivalent buttons on your behalf. By using AdErasr, you acknowledge that:

• Cookie consent is rejected automatically without per-instance confirmation.
• Some websites may restrict content or functionality when consent is rejected.
• You can whitelist specific sites to disable auto-dismissal on those domains.
• AdErasr is not responsible for any service restrictions resulting from automatic consent rejection.

5. System-Wide Protection (Aegis)

If you enable Aegis, URL filtering applies to all apps on your device that use Apple's standard networking APIs. You acknowledge that:

• Aegis may affect the functionality of non-Safari apps, including but not limited to email clients, messaging apps, news readers, and in-app browsers.
• Some apps with custom networking implementations (such as Meta, Google, and Netflix apps) may not be affected by Aegis.
• Aegis should not be relied upon to block content in critical applications (banking, healthcare, emergency services). If blocking interferes with a critical app, disable Aegis or whitelist the affected domain.
• Aegis depends on Apple's PIR relay infrastructure and AdErasr's PIR server. These services may experience downtime. When Aegis is configured to "fail open," URLs are allowed when the service is unavailable.

6. No Guarantees

Ad blocking and tracker prevention are inherently imperfect. Websites change, ad networks adapt, and new tracking methods emerge. We update filter lists regularly, but we cannot guarantee that every ad or tracker will be blocked on every website or in every app at all times. Some websites may not function correctly with content blocking enabled — use the per-site whitelist for those cases.

7. Tracker Intelligence

AdErasr's Daily Intelligence Report includes descriptions of tracker companies and their data practices. These descriptions are informational, based on publicly available information, and may contain inaccuracies. They do not constitute legal, factual, or definitive assertions about the named companies. AdErasr is not responsible for the accuracy or completeness of tracker intelligence descriptions.

8. Data Ownership

All data generated by AdErasr on your device (block statistics, tracker records, daily reports, achievement progress) belongs to you. This data is stored locally on your device and is deleted when you uninstall the app or reset statistics. AdErasr does not claim any ownership interest in your locally generated data.

9. Purchases & Refunds

AdErasr is a one-time purchase through the Apple App Store. All billing, payment processing, and refunds are handled by Apple. To request a refund, visit reportaproblem.apple.com.

10. Intellectual Property

AdErasr and its original content, features, and functionality are owned by Hartistic.

11. Open Source Attribution

AdErasr uses open-source filter lists maintained by their respective communities. These lists are used under their original licenses and we gratefully acknowledge their work:

• EasyList & EasyPrivacy (GPLv3)
• uBlock Origin Filters, Privacy, Badware, Unbreak, Quick Fixes (GPLv3)
• AdGuard Base, Mobile, Tracking Protection, Annoyances (GPLv3)

12. Website & Test Engine

The ad blocker stress test available at aderasr.com/test, including its test definitions, scoring algorithms, engine logic, user interface, and associated assets, is proprietary software owned by Hartistic. You may not copy, reproduce, reverse engineer, decompile, redistribute, or create derivative works based on the test engine or any portion of it without prior written consent from Hartistic. Automated scraping, crawling, or bulk downloading of the test engine code is prohibited.

13. Service Availability

AdErasr relies on a filter list update service to keep blocking rules current. While we strive to maintain continuous availability, we do not guarantee uninterrupted access to the update service. If the update service becomes temporarily unavailable, AdErasr will continue to function using the most recently downloaded filter lists. In the unlikely event that the update service is permanently discontinued, we will provide reasonable notice and the app will continue to function with its last-updated rules.

14. User Responsibilities

By using AdErasr, you agree to:

• Whitelist management: You are responsible for managing your whitelist. Whitelisting a site disables all protections for that site, including malware blocking.
• Custom rules: You are solely responsible for custom rules you create. They may break sites or override protective blocking rules.
• Reporting: You are encouraged to report broken websites and blocking issues via the in-app feedback or contact form.
• Prohibited conduct: You agree not to reverse-engineer, decompile, or extract the app's source code (except as permitted by law); not to use the app for any unlawful purpose; and not to interfere with the app's update infrastructure.

15. Apple Platform Dependency

AdErasr's functionality depends entirely on Apple's Safari Content Blocker API, Web Extension API, and NEURLFilter API. Apple may change, restrict, deprecate, or remove these APIs at any time. Such changes may reduce or eliminate the app's ability to block content. The developer is not liable for reduced functionality caused by iOS, Safari, or WebKit updates. Content Blocker extensions are limited to 150,000 rules each (Apple's limit).

16. Disclaimer of Warranties

THE APP IS PROVIDED ON AN "AS-IS" AND "AS-AVAILABLE" BASIS, WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED. To the fullest extent permitted by law, Hartistic disclaims all warranties, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement; any warranty that the app will be uninterrupted, error-free, or secure; any warranty regarding the accuracy or completeness of blocking; and any warranty that the app will not interfere with website functionality.

17. Limitation of Liability

To the maximum extent permitted by law, Hartistic shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from the use or inability to use the app, including but not limited to:

• Website functionality issues caused by content blocking.
• App functionality issues caused by system-wide URL filtering (Aegis).
• Service restrictions resulting from automatic cookie consent rejection.
• Failed or incomplete ad, tracker, or malware blocking.
• Inaccuracies in tracker intelligence descriptions.
• Temporary unavailability of filter list updates or PIR server infrastructure.
• Security breaches or malware infections the app failed to prevent.

Hartistic's total liability shall not exceed the amount you paid for the app.

18. Indemnification

You agree to indemnify and hold harmless Hartistic from any claims, damages, losses, or expenses arising from your use of the app, custom rules you create, whitelist decisions you make, or violation of these terms.

19. Dispute Resolution & Arbitration

Informal resolution: Before initiating formal proceedings, contact us at our contact form and attempt to resolve the dispute informally for at least 30 days.

Binding arbitration: Unresolved disputes shall be resolved by binding individual arbitration under the American Arbitration Association's Consumer Arbitration Rules, conducted in the State of Florida or via videoconference. The Federal Arbitration Act governs this provision.

Class action waiver: You and Hartistic agree that disputes will be resolved individually, not as part of any class, collective, or representative action.

Small claims exception: Either party may bring an individual action in small claims court.

Opt-out: You may opt out of arbitration by emailing support@joshuahart.io within 30 days of first using the app.

20. Governing Law

These terms are governed by the laws of the State of Florida, United States, without regard to conflict of law provisions.

21. Severability

If any provision of these terms is held unenforceable, the remaining provisions continue in full force.

22. Changes

We may update these terms from time to time. Continued use of AdErasr after changes constitutes acceptance of the new terms.
