PuracamPrivacy Policy
Last updated: 9 September 2026
Puracam is made by Pham Quoc Hoa, an individual developer. This policy explains exactly what the app does and does not collect. It is written to match what the code actually does — not a template.
The short version. Your scans never leave your device. Puracam has no account system and no server of its own. The only data sent anywhere is anonymous usage and crash diagnostics, which you can switch off in Settings.
1. What stays on your device
Everything you actually create with Puracam is stored only on your iPhone or iPad, in the app's private storage. None of it is uploaded, and I have no way to access it:
- Scans — the 3D mesh, the texture atlas, camera keyframes and depth data captured during a scan.
- Camera imagery — frames captured while scanning are used to build the texture and then stay in the scan on your device.
- Scan locations — if you grant location access, the coordinates where a scan was taken are stored with that scan so your library can be shown on a map. These coordinates are never transmitted and are not included in any analytics event.
- Your settings — preferences such as quality presets are kept locally.
Deleting a scan in the app deletes it from the device. Deleting the app removes all of it.
2. What is collected
Puracam uses two Google Firebase services. Both are limited to anonymous diagnostics about how the app performs.
Usage analytics (Firebase Analytics)
When usage sharing is enabled, the app records that certain actions happened, together with non-identifying details about them:
| Recorded | Example details |
|---|---|
| Screens opened, onboarding completed | screen name |
| Scan started, finished or abandoned | duration in seconds, number of keyframes, triangle count, capture mode, quality preset |
| Processing started, finished or failed | duration, output triangle count, voxel size, which stage failed and a category for why |
| Viewer opened, a viewer tool used | which tool |
| Export started or finished | file format, quality |
| Paywall shown, a Pro feature reached, purchase completed | which feature, which subscription product |
| A scan deleted | how old the scan was, in days |
| Coarse profile properties | a bucket for how many scans you have made, your default capture mode and preset, whether you have ever exported, whether you have Pro |
These are numbers and fixed labels only. No file names, no scan contents, no images, no coordinates, and no free text you type are ever included.
Crash and performance diagnostics (Firebase Crashlytics)
If the app crashes, a report is sent containing the crash stack trace, the device model, the operating system version and the app version, so the fault can be found and fixed.
Device identifier
Firebase assigns a random per-installation identifier so that separate events can be recognised as coming from the same app installation. It is not linked to your name, Apple Account, email or phone number, and it is reset if you delete the app.
3. What is not collected
- No advertising identifier. The app uses the analytics variant that does not read the IDFA, and ad personalisation signals are disabled in the build.
- No tracking. Puracam does not track you across other companies' apps or websites, and shares nothing with data brokers or ad networks.
- No account. There is no sign-up, so no name, email or password is collected.
- No sale of data. Your data is not sold or rented to anyone, for any price.
- No contacts, photos library, microphone or health data.
4. Your control
Usage analytics can be turned off at any time:
Settings → Share usage data
This is on by default. Turning it off stops usage events from being sent. If you would rather it were off, switch it off the first time you open the app — nothing else in Puracam depends on it, and every feature keeps working.
5. Device permissions
| Permission | Why | Required? |
|---|---|---|
| Camera | Capturing the scene and building the texture. Scanning is not possible without it. | Yes |
| Location (while using the app) | Tagging a scan with where it was taken so your library can be shown on a map. | No — decline it and everything else still works |
6. Purchases
Puracam Pro is sold as an auto-renewing subscription through Apple. Payment is handled entirely by Apple: card numbers, billing addresses and Apple Account details never pass through the app and are never visible to me. The app only learns whether an active subscription exists. Apple's handling of that transaction is covered by Apple's Privacy Policy.
7. Who else is involved
Analytics and crash data are processed by Google LLC as the operator of Firebase, acting on my instructions, and may be stored on Google servers outside your country, including in the United States. See Firebase privacy information. No other third party receives data from Puracam.
8. How long data is kept
Scans stay on your device until you delete them or remove the app — there is no expiry and no copy elsewhere. Analytics and crash records are retained by Firebase according to its retention settings, currently the default period, after which they are deleted automatically.
9. Children
Puracam is not directed at children under 13, and no data is knowingly collected from them.
10. Your rights
Because Puracam has no account and stores nothing about you on a server, most requests are things you can carry out yourself and immediately: your content is deleted by deleting scans or the app, and collection is stopped by the Settings switch above.
Depending on where you live — for example under the GDPR in the European Economic Area and the United Kingdom, or the CCPA in California — you may also have the right to ask what diagnostic data relates to your installation, to have it deleted, or to object to its processing. Write to the address below and I will respond. Because the identifier is random and not linked to you, I may need the identifier from your device to locate any records at all.
11. Changes to this policy
If the app starts collecting something new, this page will be updated and the date at the top changed before that version ships. Material changes will also be noted in the App Store release notes.
