Terms of use

Last updated: 2026-10-16

These terms apply to the Pollen app ("the app") and to our server that provides the forecasts. The app is offered by GGSHOP LIMITED, Unit 856 of Workspace B on 8/F, Tai King Industrial Building, San Po Kong, Hong Kong ("we"). Contact: ggshoplimitedco@gmail.com.

By using the app you accept these terms. The conditions for paid features are in "Pro: payment, cancellation and refunds", and the limits of the service are in "Limits and fair use". Both are part of these terms.

What the app is

• The app shows pollen forecasts from computer models, not measurements. Values are averages for an area of about 25 × 25 km and can differ from what you experience where you are.
• The app is for information only. It is not a medical device and does not give medical advice. It does not diagnose, treat or prevent any condition. Do not start, stop or change a treatment because of the app; ask your doctor or pharmacist. In an emergency call your local emergency number.
• The section "What may be triggering my symptoms" compares your own diary entries with the forecast. It shows a statistical pattern, not a cause.

Data sources

• Six species (alder, birch, grass, mugwort, olive, ragweed) come from the Copernicus Atmosphere Monitoring Service (CAMS). Contains modified Copernicus Atmosphere Monitoring Service information. Neither the European Commission nor ECMWF is responsible for any use of this information.
• Cypress, plane tree and poplar (Pro) come from Atmospore (atmospore.com).
• City names come from GeoNames (CC BY 4.0).

We do not guarantee that forecasts are complete, correct or available at every moment. A species can be "not modelled here", a day can be missing, and an update can be late.

Your diary

Your diary, places and settings are stored on your phone. You are responsible for keeping them (for example with your phone's backup or the CSV export in the app). If you delete the app or its data, we cannot restore them.

Fair use

You may not:

• use the server outside the app, collect its data automatically (scraping) or resell it;
• share the Pro connection of your device or try to bypass the limits;
• interfere with the server or the app, or reverse engineer them, except where the law allows it.

If we see such use, we may limit or block the device or purchase concerned. Where possible we will tell you first.

Free and Pro

The app is free to use with ads. Pro is an optional paid upgrade. Everything about payment, renewal, cancellation, refunds and devices is in "Pro: payment, cancellation and refunds".

App stores

If you downloaded the app from Google Play, the Google Play terms also apply. If you downloaded it from the App Store, Apple's Standard Licensed Application End User License Agreement (EULA) also applies. Apple and Google are not responsible for the app, its content, support or maintenance; we are.

Liability

We build the app with care, but we cannot promise that it will always work without errors or interruptions. As far as the law allows, we are not liable for indirect damage or for decisions you make based on a forecast. Nothing in these terms limits your rights as a consumer under the law of the country where you live, including your rights if a paid feature is faulty or not as described.

Changes

We may update the app and these terms, for example when a data source or the law changes. We will show the date of the last change at the top. If a change affects Pro in an important way, we will tell you in the app before it takes effect.

Law and complaints

These terms are governed by the law of Hong Kong. If you are a consumer, the mandatory rules of the country where you live still protect you. Please write to us first at ggshoplimitedco@gmail.com; we reply within 14 days. You can also contact the consumer protection authority in your country.
