Company and app

This Privacy Policy applies to the application CatsBlock Weather (the “App”) and to this website, published by CatsBlock Corporation (“CatsBlock Corporation”, “we”, “us”).

By downloading, opening or using CatsBlock Weather, you acknowledge that you have read this Privacy Policy and agree to it. If you do not agree, do not use the App. Use of the App is also governed by the Terms of Service.

Controller and legal bases

For the limited technical data described here, CatsBlock Corporation acts as data controller. Where the GDPR, UK GDPR, LGPD or similar laws apply, processing relies on legitimate interests in operating, securing and protecting the service from abuse and, for location, on your consent, which you can withdraw at any time in your device settings.

Data we process

CatsBlock Corporation does not run user accounts, analytics or advertising, does not sell your data and does not build user profiles. The App stores saved cities and preferences on your device. When a Cloudflare Worker data source or the Agent is used, limited technical data is processed to operate and protect the service: your IP address and approximate coordinates, as described below.

Location permission

If you allow location access, your position is read on your device to find the weather where you are. When a data source that uses the Cloudflare Worker is selected, approximate coordinates (rounded to about 1 km) are sent through it. You can revoke location permission at any time in your device settings.

Data stored on your device

Saved cities and your preferences are stored only on your device and can be removed at any time by clearing the App data or uninstalling the App.

Visual effects and touch input

Rain, snow and touch effects are drawn on your device using its graphics processor. Where you touch a weather card is used only to animate the effect on screen; touch positions are never stored, logged or sent anywhere.

Third-party public APIs

To show weather, coordinates and city searches are sent to free, public third-party services such as Open-Meteo, WeatherAPI.com, Visual Crossing and OpenWeather. Moon images and map tiles are loaded from public providers such as NASA and OpenStreetMap. These providers receive your IP address as part of the connection, are not operated by CatsBlock Corporation, and are governed by their own terms and privacy policies.

When you use the travel planner, the places you type are sent to Open-Meteo to find their coordinates, the start and destination coordinates are sent to the public OSRM routing service to calculate the route, and coordinates of points along the route are sent to Open-Meteo to get the forecast. These services are not operated by CatsBlock Corporation. The planner does not store routes on any CatsBlock Corporation server.

Cloudflare Worker proxy

When the WeatherAPI.com, Visual Crossing or OpenWeather data source or the Agent is used, requests go through a Cloudflare Worker operated by CatsBlock Corporation, which keeps API keys off your device and limits abuse. To enforce limits, a Durable Object and Cloudflare KV keep counters tied to an irreversible hash of your IP address, never the original, for at most 24 hours. Your country, derived by Cloudflare from the connection, is checked per request and not stored. No device identifier is collected. Weather responses for rounded coordinates are cached for about 15 minutes. Cloudflare may process connection data under its own terms. The Open-Meteo source does not use this proxy.

AI Agent

The Agent sends your message, the selected city and rounded coordinates through the Worker to Google’s Gemini API and public weather services, which process them under their own terms. Do not enter personal, sensitive or confidential information. Replies are AI-generated, may be inaccurate and are not professional weather, safety or emergency advice; no decision with legal or similarly significant effects is made about you. CatsBlock Corporation does not store your messages or replies. The activity panel shows real technical steps, not the AI’s reasoning.

This website

This website does not use cookies, analytics or advertising. Opening it loads fonts from Google Fonts. The Download page asks GitHub’s public API for the latest release and keeps a copy of the answer in your browser’s session storage for ten minutes. To apply the regional rules described in the Terms of Service, the site asks public IP-to-country services (api.country.is, geojs.io, ipwho.is, db-ip.com and ipapi.co) for your approximate country. Each of these services, like GitHub and Google Fonts, receives your IP address as part of the connection and follows its own privacy policy. The country result is kept in your browser’s memory only and is not stored by us. The host of this website may keep ordinary server logs.

International transfers

Data is processed on Cloudflare’s global network and by the third-party providers named in this policy, which may be located outside your country, including outside the EEA and the UK. Where required, transfers rely on the safeguards those providers offer, such as Standard Contractual Clauses.

Your rights

Depending on where you live (including under the GDPR, UK GDPR, LGPD, CCPA/CPRA and PIPEDA), you may have rights to access, correct, delete, restrict or port personal data, to object to processing and to withdraw consent. CatsBlock Corporation does not sell or share personal information and does not use it for advertising or profiling. Because it offers no accounts or contact channel and keeps only irreversible hashes that cannot be linked to you, it cannot identify you or retrieve data about you, so such requests generally cannot be fulfilled; records expire automatically. You may complain to your local data protection authority.

Children

The App is not directed to children under 16, and CatsBlock Corporation does not knowingly collect their personal data. Where local law sets a different minimum age, that age applies. If you are below it, do not use the App.

Regional restrictions

The service is not available in certain regions because of local laws, sanctions and data-transfer rules, currently including Japan, Iran, Cuba, North Korea, Syria, China, Russia and the Crimea, Donetsk, Luhansk and Sevastopol regions. Cloudflare determines your country from the connection on each request without storing it, and access is re-evaluated automatically. Bypassing these restrictions with a VPN, proxy or other means is prohibited, and you are solely responsible for complying with the laws that apply to you.

Security

We apply reasonable technical measures such as encrypted connections, request validation and rate limiting, but no system is completely secure, and we cannot guarantee that the service will be free of errors, vulnerabilities or unauthorized access.

No emergency use

Do not rely on the App or the Agent for emergencies or for safety-critical or life-critical decisions. Always follow official warnings and instructions from your local authorities.

Limitation of liability

The App and its servers are provided “as is” and “as available”, without warranties of any kind. To the fullest extent permitted by applicable law, CatsBlock Corporation is not liable for server downtime or interruptions, data leaks, security breaches, vulnerabilities, errors, inaccurate weather data, or any loss or damage resulting from the use of, or inability to use, the App or its servers, and by using the App you agree not to bring claims against CatsBlock Corporation for these reasons. Weather data accuracy is the responsibility of the third-party providers. Nothing in this policy excludes liability that cannot be excluded by law or limits rights you have under mandatory data protection or consumer laws.

Indemnification and governing law

To the fullest extent permitted by law, you agree to indemnify and hold harmless CatsBlock Corporation from claims, losses and expenses arising from your misuse of the App, your breach of this policy or applicable law, or your use of the service from a restricted region. This policy is governed by the laws of the jurisdiction where CatsBlock Corporation is established, without prejudice to mandatory consumer and data protection rules of your country of residence. If a provision is unenforceable, the rest remains in force.

No individual support

CatsBlock Corporation does not provide individual support and offers no contact channel. Requests, questions or messages cannot be answered.

Changes to this policy

We may update this policy at any time. Continuing to use the App after an update means you accept it. Last updated: 2026-11-03.

Acceptance of the terms

By using CatsBlock Weather (the “App”) or this website, published by CatsBlock Corporation, you agree to these Terms of Service and to the Privacy Policy. If you do not agree, do not use the App. You can review these terms at any time on this page and in the App under Settings.

Who can use the App

The App does not verify age. Where local law sets a minimum age for using the App, that age applies. The Agent is an AI and is not recommended for children under 12. If you let a child use the App, you are responsible for their use.

Getting and updating the App

The App is distributed as an APK file through the GitHub Releases of the official repository, linked from this website. It is not distributed through Google Play, so Android and Play Protect may show warnings when you install it. Install only files obtained from this website or the official repository, and check them as described on the Download page. The built-in updater downloads new builds from the same releases and Android asks for your confirmation before installing. You are responsible for the security of your own device.

The source code is viewable on GitHub. Unless the repository states otherwise, viewing the code does not grant a license to copy, modify or redistribute it.

The Agent

The Agent is an AI that answers questions about the weather. Its replies are generated automatically, may be inaccurate or incomplete, and are not professional weather, safety or emergency advice. Always check the official forecast and warnings from your local authorities.

Agent usage limits

Agent usage is limited by the number of tokens it spends, up to 2,500 tokens per device within 24 hours. When the limit is reached, the message box is replaced by a notice with the time it will return. Messages sent in quick succession are queued, and sending too many messages in a short time blocks further messages for one minute.

Acceptable use

Do not use the Agent for anything inappropriate, unlawful or against these terms, including crimes, harassment, attempts to bypass its rules or safety measures, and requests unrelated to the weather. Messages that violate these terms are not answered and are marked as a violation.

Do not attempt to bypass limits, impersonate other devices, overload the servers or access the service by automated means.

Servers and third-party services

The App relies on servers and services operated by CatsBlock Corporation and third parties, including a Cloudflare Worker, Google’s Gemini and public weather and map providers, which follow their own terms. To enforce fair limits for each device, a one-way hash of your device’s characteristics is used as described in the Privacy Policy. We may block or limit access to prevent abuse or to comply with the law.

Availability and regions

The service is provided when available and may change, be interrupted or be unavailable in some regions because of local laws, sanctions and data-transfer rules. Downloads from this website may be disabled based on your approximate country, and bypassing a restriction with a VPN, proxy or other means is prohibited. We may add, change or remove features, limits and data sources at any time.

Weather information and emergencies

Forecasts, alerts and other weather data come from third-party providers and may be late, incomplete or wrong. Do not rely on the App or the Agent for emergencies or for safety-critical or life-critical decisions. Follow official warnings and instructions from your local authorities.

Disclaimer

The App, the website and the Agent are provided “as is” and “as available”, without warranties of any kind.

To the fullest extent permitted by law, CatsBlock Corporation is not liable for any indirect, incidental or consequential damages, or for decisions made based on the App or the Agent. Nothing in these terms excludes liability that cannot be excluded by law or limits rights you have under mandatory consumer or data protection laws.

Indemnification and governing law

To the fullest extent permitted by law, you agree to indemnify and hold harmless CatsBlock Corporation from claims, losses and expenses arising from your misuse of the App, your breach of these terms or applicable law, or your use of the service from a restricted region. These terms are governed by the laws of the jurisdiction where CatsBlock Corporation is established, without prejudice to mandatory consumer and data protection rules of your country of residence. If a provision is unenforceable, the rest remains in force.

Suspension and termination

We may suspend or block access to the App or the Agent, including for violations of these terms. You can stop using the App at any time by uninstalling it.

No individual support

CatsBlock Corporation does not provide individual support and offers no contact channel.

Changes to these terms

We may update these terms at any time. Continuing to use the App after an update means you accept it. Last updated: 2026-11-03.
