Welcome to Heatprint ("the app", "we", "us"). These Terms govern your use of the iOS app and any related services we provide. Please read them carefully — by downloading, installing, or using the app, you agree to be bound by these Terms.
Heatprint is an iOS app published by Mykola Viunyk as an individual sole proprietor based in California, USA. You can reach us at:
Email: vuniqueprodaction@gmail.com
Mailing address: 421 N Pass Ave, Burbank, California, USA
We grant you a personal, non-exclusive, non-transferable, revocable license to install and use Heatprint on Apple devices you own or control, subject to the Apple Media Services Terms and Conditions. You may not reverse engineer, decompile, sublicense, resell, or modify the app, except to the extent Apple's terms or applicable law expressly allow.
Heatprint is free to download and use. Certain tools — including side-by-side facility comparison, citation export, multi-year climate trends, the operator portfolio view, alternate map styles, the offline cache, and unlimited favorites — are available via the optional "Heatprint Pro" unlock for a one-time purchase of $19.99 USD (price may vary by region).
The Pro unlock is a non-consumable in-app purchase processed by Apple. Your purchase is tied to your Apple ID. You can restore it on any device signed into the same Apple ID by tapping the Restore button on the paywall.
We do not process refunds directly. All refund requests must be submitted to Apple at https://reportaproblem.apple.com.
Heatprint displays data fetched from third-party public sources, including (but not limited to):
NOAA U.S. Climate Normals (1991–2020) and NOAA Climate Data Online
U.S. EPA eGRID (electric-grid emissions data)
U.S. EPA AirNow (current air quality)
USDA / University of Nebraska–Lincoln U.S. Drought Monitor
PeeringDB (data-center facility metadata)
Every figure in the app cites its primary source. While we make a good-faith effort to surface accurate, up-to-date public data, we do not warrant the accuracy, completeness, or timeliness of any figure. The data providers listed above are responsible for their own data; Heatprint simply displays what they publish. You should consult primary sources directly before relying on any figure for journalism, research, regulatory, commercial, or other professional purposes.
Some data sources (NOAA, EPA AirNow) require a free API key or token from the data provider. You enter these in the app's Settings. The tokens are stored locally on your device. Heatprint does not transmit your tokens to any server we control; they are sent only to the data provider as part of the API request you initiated by opening a facility's detail view. You are responsible for keeping your tokens private and for abiding by each provider's terms of use.
You agree not to use Heatprint to:
Violate any law or regulation
Misrepresent the data shown in the app, including by stripping citations when republishing
Attempt to circumvent the Pro paywall, including by reverse-engineering entitlement checks
Use the app in a way that disrupts or abuses the third-party services it relies on (e.g., automated scraping at a rate that violates the data provider's terms)
The app's code, design, copy, branding, and original visualizations are owned by Mykola Viunyk. The underlying public data remains the property of (and is subject to the terms of) the respective data providers. Apple, iOS, App Store, and related marks are trademarks of Apple Inc.
THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT ANY DATA SHOWN IS ACCURATE OR CURRENT.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, MYKOLA VIUNYK AND Heatprint WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUES, DATA, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF THE APP. OUR TOTAL LIABILITY TO YOU FOR ANY CLAIM ARISING OUT OF OR RELATED TO THESE TERMS OR THE APP IS LIMITED TO THE AMOUNT YOU PAID FOR THE APP IN THE TWELVE MONTHS PRECEDING THE CLAIM (OR $50 USD, WHICHEVER IS GREATER).
If you are a consumer in a jurisdiction that does not allow certain limitations of liability (including parts of the EU, the UK, and certain U.S. states), the limitations above apply only to the extent permitted by the law of that jurisdiction. Your statutory consumer rights remain unaffected.
We may update these Terms from time to time. When we do, we will change the "Last updated" date above. If the changes are material, we will surface a notice in the app. Continued use of the app after a change constitutes acceptance of the updated Terms.
These Terms are governed by the laws of the State of California, USA, without regard to its conflict-of-law principles. Any dispute will be resolved in the state or federal courts located in Los Angeles County, California, unless your local consumer-protection law gives you the right to bring the claim in your home jurisdiction (in which case that right applies).
If you and we cannot resolve a dispute informally, please contact us first at vuniqueprodaction@gmail.com before bringing any formal claim. We will make a good-faith effort to respond within 30 days.
