Privacy Policy

Effective July 26, 2026

Trunk: Smart Packing Assistant (“Trunk”, “we”, “us”, or “our”) respects your privacy. This Privacy Policy explains how we handle your data when you use our mobile application and when you visit our website at trunkmobile.app. Unless a section says otherwise, what follows describes the app; the website is covered in section 3.

1. Information We Collect

Trunk has no user accounts, and we do not build a profile of you. Your trips, items, packing lists, bags, and photos are stored locally on your device and are not uploaded to us.

We do not collect:

• Your name, email address, or contact information
• Your device’s advertising identifier
• Your GPS or precise location — Trunk never requests location permission and never uses your device’s location services. (Our analytics provider does estimate an approximate area, typically your city, from your network connection — see section 3.)

Some things do leave your device. Two are about weather: when you search for a destination, what you type is sent to a location lookup service so it can suggest matching places, and when we show a forecast, the destination’s coordinates and the trip’s date range are sent to a weather service. Both are described in section 2. A third is the limited usage and crash information described in section 3, which you can turn off. Device backups are a separate matter, covered in section 6.

2. Weather and Third-Party Services

Trunk uses these services. We send none of them your name, email, or any account identifier — Trunk has none to send.

• WeatherAPI — as you type a destination while planning a trip, what you’ve typed is sent to WeatherAPI so it can suggest matching places and turn your choice into structured location data (city, region, coordinates). Suggestions begin after two characters, so partial text is sent as you type. Nothing else is sent — no GPS, no background location.
• Apple WeatherKit (iPhone and iPad) — to fetch the forecast for a trip, your destination’s coordinates and the trip’s start and end dates are sent to Apple. Apple’s handling of that request is governed by Apple’s own privacy policy.
• Our weather service (Android) — Apple WeatherKit is not available on Android, so on Android the same request (destination coordinates and trip dates) goes to a small service we operate on Amazon Web Services, which forwards it to Apple’s weather data and returns the forecast. This request is not tied to any account or persistent identifier: the app obtains temporary, anonymous AWS credentials that are discarded when the app closes. We do not use these requests to build a profile. The coordinates are used only to fetch that forecast and are not stored. We do not log your IP address on this service; our operational logs contain only error diagnostics and request identifiers, and are automatically deleted after 14 days.
• Apple App Store / Google Play — if you tap “Rate Trunk”, the store’s own review prompt is shown. We receive no information from it, and we never see what you rate or write.

We do not share any personal information with any of these services, and we do not sell data to anyone.

3. Analytics and Crash Reporting

To understand which features people actually use and to find and fix bugs, Trunk collects a limited amount of information about how the app is used and about crashes. This is on by default, and you can turn it off at any time — see “Your choice” below.

What we collect

• How the app is used — which screens you open and which features you use, recorded as simple events (for example, that a trip was created, a photo was attached, or a saved list was applied). These events never include anything you typed: no trip names, item names, notes, destinations, or coordinates.
• Your device and app version — basic technical details such as your device brand and model, screen size, operating-system version, and which version of Trunk you’re running. We use this to know which devices and versions to support and test against.
• Crash and error reports — when the app crashes or hits an error, we receive a technical report so we can fix it: the error and its stack trace, your device model, operating-system version, and the app version. These reports do not include your trips, items, packing lists, or photos.
• A random per-install identifier — so we can tell repeat visits apart (for example, whether people come back to plan a second trip) without knowing who you are. This is not an advertising identifier, and it is not linked to your name, email, or any account — Trunk has none.

We never learn who you are. This information is not tied to your identity, and we do not use it to track you across other apps or websites.

Location. Trunk never requests location permission and never uses your device’s location services — as noted in section 1. Our provider (Google) does receive your device’s IP address as an ordinary part of the network request, and uses it to estimate an approximate location, typically down to the city, which is kept as part of the usage statistics. The IP address itself is then discarded. We never receive or store your IP address, and this estimate is not precise location data — it is derived from your network connection, not from your device. This is separate from our weather service in section 2, which does not log your IP at all.

Who handles it. This is provided by Google Analytics for Firebase and Firebase Crashlytics, part of Google, and is governed by Google’s privacy policy. Google keeps the detailed records for up to 14 months, after which they are deleted. Aggregate counts and trends — totals that cannot be traced back to any individual install — may be kept longer. We do not sell it, and we do not share it beyond what is needed to provide these services.

Your choice. You can turn all of this off in Settings, under “Share usage data.” Turning it off stops both usage analytics and crash reporting. So that we can measure how many people opt out, the app records that single setting change at the moment you turn it off, and then collects nothing further. You can turn it back on at any time.

Our website. Everything above describes the app. Our website at trunkmobile.app uses Google Analytics too, and it differs in one important way: it is off until you say yes. On your first visit a banner asks whether you want to allow it. Until you choose “Accept”, Google Analytics is not loaded at all — no cookie is stored, no page view is sent, and nothing about your visit reaches Google. If you choose “Decline”, we count nothing at all, and you can keep reading the site exactly as before.

If you do accept, we see which pages you viewed, roughly where you are (an approximate area, typically your city, which Google estimates from your IP address in the same way described above), what browser and kind of device you used, and whether you arrived from a search engine, a link elsewhere, or by typing the address directly. We also record when someone taps a link to the App Store, so we can tell how many visitors go on to look at the app. We never learn who you are — the website has no accounts and no sign-in, and we ask you for nothing.

Accepting stores a Google Analytics cookie (_ga) in your browser. It holds a random identifier that tells your browser apart from other visitors’, so that your second visit is not counted as a second person; it does not tell us your name and is not used to follow you to other websites. Your answer to the banner is remembered separately in your browser’s local storage, so you are not asked again on every page. To change your answer, clear this site’s cookies and site data in your browser settings — the banner will then ask again on your next visit. As with the app, this is handled by Google, which keeps the detailed records for up to 14 months before deleting them.

4. Photos and Camera

You can optionally attach a photo to an item, either by taking one or choosing one from your photo library. Trunk asks for camera or photo access only at the moment you use that feature, and you can decline.

Photos you attach are copied into Trunk’s own storage on your device. They are never uploaded to us or to any third party, and Trunk does not read your photo library beyond the specific image you select.

5. In-App Purchases

Trunk may in the future offer in-app purchases (for example, a Pro subscription) through the Apple App Store or Google Play Store. All payment processing is handled by those platforms. We do not collect or store payment information ourselves.

6. Data Storage and Security

Your app data is stored locally on your device using the operating system’s standard app storage. You are responsible for backing up your device.

If you delete the app, the application data stored on your device — including your trips, items, packing lists, and any photos you attached — is removed with it.

If you have device backups turned on, such as iCloud or Google, your Trunk data is included in those backups, the same as other apps’ data. That is deliberate: Trunk has no accounts and no cloud sync, so a device backup is what stands between you and losing your trips and photos if your phone is lost, damaged, or replaced. Those backups are held by Apple or Google under their own policies rather than by us, which also means a copy in a backup is not removed by deleting the app — removing it follows Apple’s or Google’s process.

Requests to weather services are sent over encrypted connections (HTTPS).

7. Deleting Your Data

Because your trips, items, packing lists, and photos stay on your device and we keep no copy of them, there is no deletion request to make of us for that content. Usage and crash reporting works differently — see the last bullet below.

• Individual entries — you can delete a trip, item, bag, saved packing list, or an attached photo inside the app at any time. Deleting a photo removes Trunk’s copy from your device; if you chose that photo from your photo library, the original there is not affected.
• Everything at once — delete the app. That removes the application data stored on your device, subject to the device-backup note in section 6.
• Weather requests — nothing to delete. Destination coordinates are used only to fetch a forecast and are not stored, and our operational logs, which do not contain your IP address, are automatically deleted after 14 days.
• Usage and crash data — turning off “Share usage data” in Settings stops any further collection immediately (see section 3). The detailed records are held by Google for up to 14 months and then deleted automatically; aggregate counts, which cannot be traced back to any individual install, may be kept longer. Because it is never linked to your identity, we have no way to tell which records came from you, so we cannot delete one person’s history on request — that is the trade-off of not knowing who you are.
• Website analytics — if you declined the banner on trunkmobile.app, or never answered it, nothing was collected and there is nothing to delete. If you accepted, clearing this site’s cookies and site data in your browser removes the identifier from your browser, so your next visit is not connected to your previous ones. Records already held by Google are deleted automatically on the same 14-month schedule, and for the same reason as above we cannot single out one person’s history on request.

If you have a question about any of this, contact us at the address in section 10.

8. Children’s Privacy

Trunk is not directed at children under the age of 13. We do not knowingly collect any data from children.

9. Changes to This Policy

We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage users to review this page periodically for any updates. Continued use of the app after changes are made constitutes acceptance of the revised policy.

If we introduce features that materially affect how your data is handled — such as cloud storage or user accounts — we will provide additional notice and may require you to accept the updated terms before continuing to use those features.
