Part 1 – Privacy Policy

1. Summary

We collect the data that the Apps need to work: your account, the data you save (sessions, shots, rifle and bullet profiles), and information about the Athlon devices you connect.
We use your location only to get local weather for your ballistic calculations. We do not store your location on our servers.
We collect crash reports and app usage statistics to fix problems and improve the Apps.
We do not sell your data. We do not show ads. We do not use an advertising ID.
You can delete your account and its data at any time (see Delete your account).

2. Data we collect

Account data. When you create an account, we collect your name, email address and password. We store your password only in a protected (hashed) form. If you sign in with Google, we receive your name and email address from Google. Data you save in the Apps. This includes:

Chronograph sessions and shots: shot velocities, dates and times, session names and notes, and the weather values saved with a session.
Rifle and bullet profiles: for example bullet weight, ballistic coefficient, velocity, sight height, twist rate and zero distance.
Information about your Athlon chronographs: device name, serial number, firmware version and Bluetooth address.

We store this data with your account so that you can use it on another phone and restore it after a reinstall. Location. When you use local weather, the App uses your phone’s precise location to get the current temperature, pressure, humidity and altitude for your location from our weather service provider. We do not store your location on our servers. Android also requires location permission to search for nearby Bluetooth and Wi-Fi devices; the Apps use it only for that search. Athlon device connections. When you connect an Athlon chronograph (Bluetooth) or an Athlon thermal scope (Wi-Fi), the App reads information such as the device name, serial number, firmware version, Wi-Fi network name and device MAC address. We use it to connect to the device, show device details and check for firmware updates. To check for updates, the App sends the device model and firmware version to our servers. Photos and videos from thermal scopes. Photos and videos that you download from a thermal scope are saved on your phone only. We do not upload them. Crash reports and diagnostics. If an App crashes or has an error, we receive a crash report through Google Firebase Crashlytics and Sentry. A report contains technical information such as the phone model, Android or iOS version, App version, the error details, a random installation identifier and a one-way (hashed) form of your account identifier. It does not contain your name or email address. App usage statistics. We use Google Firebase Analytics to understand which features are used, so that we can improve the Apps. This uses an app-instance identifier. It does not use an advertising ID. Feedback and support. When you send feedback from the App, we receive your message, any diagnostic details you choose to include, and your account email address so that we can reply. When you email us, we receive your email and its content.

3. How we use your data

To provide the Apps: save and sync your sessions and profiles, connect to your Athlon devices, calculate ballistic solutions with local weather, and deliver firmware updates.
To fix crashes and errors, and to keep the Apps and your account secure.
To understand how the Apps are used and improve them.
To answer your feedback and support requests.
To meet our legal obligations.

We do not use your data for advertising, and we do not sell or rent your data.

4. Who we share data with

We share data only with service providers that help us run the Apps, and only for the purposes above:

Microsoft Azure – hosting and storage of your account and saved data.
Google Firebase (Crashlytics and Analytics) – crash reports and app usage statistics.
Sentry – error and performance monitoring.
Weatherstack – current weather for your location. It receives your location at the time of the request.
Google Sign-In – only if you choose to sign in with Google.

We may also disclose data if the law requires it, to protect the rights and safety of our users or of Athlon Optics, or as part of a merger or sale of our business, in which case this policy continues to apply.

5. Storage and security

Data is sent between the Apps and our servers in encrypted form (HTTPS). Our servers are operated by Microsoft Azure. Your data may be processed in the United States and in other countries where our service providers operate.

6. How long we keep data

Account data and the data you save: for as long as your account exists. When you delete your account, we delete it within 30 days.
Crash reports and usage statistics: kept by our providers for a limited time (normally up to 90 days for crash reports), then deleted.
Feedback and support emails: for as long as we need them to answer and to improve the Apps.
Data we must keep by law: only for as long as the law requires.

7. Your choices and rights

You can view and change your saved data in the Apps, and export sessions from the App.
You can turn off location, Bluetooth or other permissions in your phone settings. Some features (for example local weather or device connection) will not work without them.
Depending on where you live, you may have the right to access, correct, delete or receive a copy of your personal data, and to object to some uses. To make a request, email us at [email protected].

8. Delete your account

In the App: first delete your chronographs in Menu → Manage Devices (this deletes their sessions and shots from our servers), then open Menu → Account → Delete Account. Without the App: send an email to [email protected] from the email address of your account, with the subject “Delete my account”. We will confirm the request and delete your account within 30 days. What we delete: your account, your rifle and bullet profiles, your chronograph sessions and shots, your chronograph device records, and feedback linked to your account. What we keep: crash reports and usage statistics that contain only a hashed or random identifier, until our providers delete them (normally within 90 days), and any data that we must keep by law.

9. Children

The Apps are intended for adults aged 18 and over. We do not knowingly collect data from children. If you believe a child has given us personal data, contact us and we will delete it.

10. Changes to this policy

We may update this policy. We will change the effective date at the top of this page, and we will tell you in the App about important changes.

Updates to the App and Changes to This Agreement. Athlon Optics may change this Agreement at any time. Using the App after the changes become effective means you agree to the new terms.

Class Action Waiver. We hope we never have a dispute, but if we do, you and Athlon Optics agree to try for 60 days, upon receipt of a Notice of Dispute, to resolve it informally.

If you have a dispute that Athlon Optics’ customer service representatives can’t resolve and you wish to pursue a claim, you must first send an individualized Notice of Dispute to Athlon Optics. This Notice of Dispute is a prerequisite to initiating any lawsuit. No statute of limitations will be tolled. This section and those that by their terms apply after the Agreement ends will survive any termination or cancellation of this Agreement. You may not assign your rights or obligations under this Agreement or transfer any rights to use the App. All parts of this Agreement apply to the maximum extent permitted by relevant law. If a court holds that Athlon Optics can’t enforce a part of this Agreement as written, Athlon Optics may replace those terms with similar terms to the extent enforceable under the relevant law, but the rest of this Agreement won’t change. Governing Law. This Agreement is entered into in Johnson County, Kansas. Unless expressly agreed to the contrary in an agreement, this Agreement shall be governed by and construed under the laws of the State of Kansas, without reference to its conflicts of law principles, and the parties hereby submit to the sole and exclusive jurisdiction of the District Court of Johnson County, Kansas or the United States District Court for the District of Kansas. The parties irrevocably consent to personal jurisdiction in both of these courts. Enforcement and Termination. If you violate any term of this Agreement, Athlon Optics may terminate this Agreement and stop providing the App to you. When investigating alleged violations of this Agreement, Athlon Optics reserves the right to review your data in order to resolve the issue. However, Athlon Optics cannot monitor the entire App and makes no attempt to do so. Entire Agreement.
