BestWinter is built for people who want to think about snow, mountains and timing — not about being tracked on the way there. This Privacy Notice explains what we do (and very deliberately do not do) with your information.
1. Who is behind BestWinter?
BestWinter is developed and published by Bradley Marc Copson, operating through Trendflux Ltd (“we”, “us”).
2. What we do not collect
BestWinter is designed so that ski conversations stay between you and the app:
- No address book uploads.
- No social graph or “friends” list.
- No cross-user messaging or sharing spaces.
- No attempt to reconstruct who you are from your messages.
We do not require you to tell us your real name, passport details, home address, or anything similar in order to use the core experience of the app.
3. The quiet identifier that keeps the lights on
To keep the app online, improve reliability and send optional push notifications, we use technical identifiers. Think of them as a lift pass number rather than a full dossier:
- An anonymous unique ID generated by the app and stored on your device.
- Device and app information that platforms typically provide (such as iOS version, device model, crash diagnostics).
This ID is not meant to describe you as a person. It simply tells our systems that “the same skier came back”, so we can measure whether a feature is useful and deliver notifications to the right device.
4. Analytics and push services we rely on
BestWinter uses a small set of specialized third‑party services:
- Singular – for privacy‑aware analytics, so we know if people actually use new features instead of guessing.
- OneSignal – to deliver optional, targeted push notifications such as trip reminders or feature updates.
Both services receive the anonymous identifiers mentioned above and technical device data. They do not receive your conversations with BestWinter as a chat log to profile you as a person.
5. How AI comes into the picture
When you talk to BestWinter, your prompts and context are sent to the OpenAI API so that the model can generate a helpful response. We treat this as sensitive travel planning data, not marketing copy.
The OpenAI API is used only to generate responses for you in the app. We do not use your ski chats to build our own advertising audiences or social profiles, and we do not sell conversation logs.
6. People do not see each other’s data
BestWinter is intentionally single‑player:
- Users do not message or follow each other inside the app.
- Your trips are not shared with strangers by default or surfaced in a public feed.
- Any export or sharing you choose to do (for example, sending a screenshot to a friend) happens through your own device tools.
7. Data retention
We aim to keep only what is needed to run the service safely and to understand if people still find it useful. Conversation data may be stored for a period of time so that you can return to earlier trips and so we can improve the product, but we do not keep it forever without reason.
8. Your choices
You can usually:
- Reset or delete the app’s local data from your device.
- Control push notifications from your system settings.
- Ask us to review or remove stored data where legally possible.

10. Changes to this notice
If we change how we handle data, we will update this page and, for significant changes, communicate inside the app. We prefer clear, occasional updates over fine print that quietly drifts.
