EULA
HowlAlert End User License Agreement.
Last updated: May 30, 2026
This End User License Agreement ("Agreement") is between you and MrDemonWolf, Inc. ("MrDemonWolf," "we," "us") and governs your use of the HowlAlert applications and related push-notification service (the "App"). By installing or using the App, you agree to this Agreement. If you do not agree, do not use the App.
1. The App is open source (GPLv3) — what this Agreement covers
The HowlAlert source code is licensed to everyone under the GNU General Public License v3.0 ("GPLv3"). Your rights to use, copy, modify, and redistribute the source code and your own builds are governed by the GPLv3 and nothing in this Agreement limits those rights for the code.
This Agreement governs the things the GPLv3 does not: the official binary builds we distribute (via the App Store and our signed DMG), the paid subscription features and server service we operate, and our trademarks and brand. Where this Agreement and the GPLv3 conflict as to the code, the GPLv3 controls.
2. License to the official build
Subject to this Agreement, we grant you a personal, non-exclusive, revocable license to install and use the official build of the App on devices you own or control, in accordance with the usage rules of the store it was obtained from. You remain free to build and run the App yourself under the GPLv3.
3. Subscriptions, trials, and billing (paid features)
Some features require a paid subscription, sold through Apple In-App Purchase:
- HowlAlert Pro — US$4.99 / month.
- HowlAlert Max — US$29.99 / year.
Both unlock the same features; neither tier is better than the other. Both include a 7-day free trial for new subscribers.
- Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period. Your Apple account is charged for renewal within 24 hours before the period ends.
- Manage or cancel anytime in your Apple ID → Subscriptions settings. Any unused portion of a free trial is forfeited when you purchase a subscription.
- Prices may vary by region and are shown at purchase. Billing, refunds, and cancellations are handled by Apple under Apple's terms.
4. Acceptable use
You agree not to: use the App unlawfully; attempt to gain unauthorized access to the Service or other users' data; interfere with or disrupt the Service; or use the App to violate any third party's terms (including Anthropic's). Modifying and redistributing the code under the GPLv3 is expressly permitted and is not a breach of this section.
5. Trademarks
"HowlAlert," "MrDemonWolf," the wolf mark, and associated logos are trademarks of MrDemonWolf, Inc. The GPLv3 does not grant any trademark rights. If you redistribute a modified version, you must use a different name and logo.
6. Not affiliated with Anthropic
HowlAlert is independent. "Claude" and "Claude Code" are trademarks of Anthropic, PBC, used here only to describe compatibility. HowlAlert is not affiliated with, endorsed by, or sponsored by Anthropic. Your use of Claude Code is governed by Anthropic's own terms.
7. Disclaimer of warranty
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE APP AND SERVICE ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. Usage figures are estimates and may be inaccurate; do not rely on them as authoritative limits. (This mirrors GPLv3 §§15–16 for the code.)
8. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, MRDEMONWOLF WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR LOSS OF DATA OR PROFITS, ARISING FROM YOUR USE OF THE APP. OUR TOTAL LIABILITY WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM OR US$50. Some jurisdictions do not allow these limits, so they may not apply to you.
9. Termination
This Agreement applies while you use the App. We may suspend the paid Service for breach. Your rights to the source code under the GPLv3 survive and are unaffected.
10. Governing law
This Agreement is governed by the laws of the State of Wisconsin, USA, without regard to conflict-of-laws rules, except where your local consumer-protection law provides otherwise.
11. Changes
We may update this Agreement; material changes will be posted with a new "Last updated" date.

Schedule A — Apple App Store required terms
For builds obtained from an Apple App Store, the following apply and prevail over any conflicting term above:
- Acknowledgement. This Agreement is between you and MrDemonWolf only, not Apple. Apple is not responsible for the App or its content.
- Scope. Your license is limited to use on Apple-branded devices you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.
- Maintenance and support. MrDemonWolf is solely responsible for support; Apple has no obligation to furnish any support or maintenance.
- Warranty. MrDemonWolf is solely responsible for any product warranties. If the App fails to conform to any applicable warranty, you may notify Apple for a refund of the purchase price (if any); Apple has no other warranty obligation.
- Product claims. MrDemonWolf, not Apple, is responsible for addressing any claims relating to the App.
- Intellectual property. In the event of a third-party IP infringement claim regarding the App, MrDemonWolf, not Apple, is responsible for the investigation, defense, settlement, and discharge.
- Legal compliance. You represent that you are not located in a U.S.-embargoed country or on any U.S. government restricted-party list.
- Third-party terms. You must comply with applicable third-party terms when using the App (including Anthropic's terms for Claude Code).
- Third-party beneficiary. Apple and its subsidiaries are third-party beneficiaries of this Agreement and may enforce it against you.
