Terms of Use

Weather for photographers · Last updated: April 18, 2026

These Terms of Use ("Terms") govern your access to and use of the Atmos mobile application ("App"), developed and operated by Matthew Raifman ("we," "us," or "our"). By downloading or using the App, you agree to be bound by these Terms. If you do not agree, please do not download or use the App.

1. Eligibility

You must be at least 13 years of age to use Atmos. By using the App, you represent that you are at least 13 years old and have the legal capacity to enter into a binding agreement. If you are under 18, you represent that you have your parent's or legal guardian's permission to use the App.

2. License to Use

Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to download and use the App on Apple-branded devices that you own or control, solely for your personal, non-commercial purposes. You may not:

Copy, modify, adapt, translate, or create derivative works of the App;
Reverse-engineer, disassemble, decompile, or attempt to extract the source code of the App;
Sell, resell, rent, lease, sublicense, or otherwise transfer the App or your rights under these Terms;
Remove, obscure, or alter any proprietary notices, labels, or marks on the App.

3. Subscriptions and Billing

Atmos offers an auto-renewing subscription that unlocks the full set of 15 photography genre forecasts. The subscription price is displayed in the App prior to purchase and may vary by region and currency.

Payment: Charged to your Apple ID at the time of purchase confirmation.
Auto-renewal: Your subscription automatically renews at the end of each billing period unless you turn off auto-renewal at least 24 hours before the renewal date.
Renewal notice: Your Apple ID account is charged for renewal within 24 hours prior to the end of the current billing period at the current subscription price.
Managing subscriptions: You can manage and cancel your subscription at any time through Settings → [Your Name] → Subscriptions → Atmos on your iPhone. Cancellation takes effect at the end of the then-current billing period; no partial-period refunds are provided.
Free trial: If a free trial is offered, any unused portion of the trial period is forfeited upon purchase of a paid subscription.
Price changes: We reserve the right to change subscription pricing. We will provide reasonable notice of any price changes through the App or by email. Continued use of the App after a price change constitutes your acceptance of the new price.

4. Accuracy of Forecasts and Safety

Atmos provides shooting-condition forecasts derived from third-party weather data providers including NOAA, Pirate Weather, and Open-Meteo. All forecasts are probabilistic estimates and are inherently uncertain. Atmospheric conditions can change rapidly and without warning.

Atmos is designed for photography planning purposes only. Do not use Atmos to make life-safety decisions. For severe weather, flooding, aviation, marine, or emergency situations, always consult official sources such as the National Weather Service (weather.gov) or your local emergency management authority.

We make no warranty, express or implied, regarding the accuracy, completeness, timeliness, or reliability of any forecast data displayed in the App.

5. Acceptable Use

You agree to use the App only for lawful purposes and in a manner consistent with these Terms. You agree not to:

Use the App in any way that violates applicable local, national, or international law or regulation;
Attempt to gain unauthorized access to any part of the App, its servers, or any related systems;
Use automated tools to scrape, mirror, or extract data from the App at scale;
Resell, redistribute, or commercially exploit data obtained through the App without our written consent;
Interfere with or disrupt the integrity or performance of the App or its underlying infrastructure.

6. Intellectual Property

The App, including its design, interface, scoring algorithms, branding, and all original content, is owned by Matthew Raifman and protected by United States and international copyright, trademark, and other intellectual property laws. Third-party weather and astronomical data displayed in the App is owned by the respective providers and used under their terms. Nothing in these Terms transfers any intellectual property rights to you.

7. Third-Party Services

The App integrates with third-party services including Pirate Weather, Open-Meteo, NOAA, RevenueCat, and Apple. Your use of these services through the App is subject to their respective terms and privacy policies. We are not responsible for the availability, accuracy, or practices of any third-party service.

8. 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 APPLICABLE LAW, WE DISCLAIM ALL WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS, OR THAT ANY DEFECTS WILL BE CORRECTED.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL MATTHEW RAIFMAN OR ATMOS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR USE, ARISING OUT OF OR IN CONNECTION WITH YOUR ACCESS TO OR USE OF (OR INABILITY TO ACCESS OR USE) THE APP, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL CUMULATIVE LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR YOUR USE OF THE APP SHALL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNT YOU PAID TO US FOR THE APP IN THE TWELVE MONTHS PRECEDING THE CLAIM, OR (B) USD $10.

You agree to indemnify, defend, and hold harmless Matthew Raifman and Atmos from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to your use of the App, your violation of these Terms, or your violation of any third party's rights.

11. Termination

We may suspend or terminate your access to the App at any time, with or without cause or notice, including for violation of these Terms. You may stop using the App at any time by deleting it from your device. Termination does not entitle you to a refund of any prepaid subscription fees. Sections 6, 8, 9, 10, 12, and 13 will survive termination of these Terms.

12. Governing Law and Dispute Resolution

These Terms are governed by and construed in accordance with the laws of the State of California, United States, without regard to its conflict-of-law provisions. Any dispute arising out of or relating to these Terms or the App shall be resolved exclusively in the state or federal courts located in California, and you consent to personal jurisdiction in those courts.

13. Apple-Specific Terms

You acknowledge that these Terms are between you and Matthew Raifman / Atmos only, and not with Apple Inc. Apple is not responsible for the App or its content.
