CollectionLog (“the app”) is a private catalogue for any kind of personal collection — records, comics, watches, building sets, cards, perfume, or anything you define yourself — published by Baron Mobile Games (“we”, “us”). This policy explains what information the app handles, why, and what choices you have. It applies to the CollectionLog Android application distributed through Google Play.
Everything you catalogue stays on your phone. There is no account to create, no server to sync to, and no way for us to see what you own. The app works offline; the only thing it uses the internet for is showing advertisements, and our advertising provider collects some device data to deliver them. That is the only data collection involved, and it never includes anything you record in the app.
The app saves the following locally, in its own private storage:
| What | Why |
|---|---|
| Your collections: a name, an icon and colour, the custom fields you define for that collection (their labels, types, options and whether they are required), a cover item and the order you keep them in | Giving each kind of collection its own shape |
| Your items: title, the collection they belong to, and optionally the purchase date, price paid, estimated value, currency, condition, notes, the values of your custom fields, whether the item is on your wishlist, and its position in the gallery | The catalogue itself, and the totals and growth chart built from it |
| Photos: copies of the photos you add to an item, a small thumbnail of each, their dimensions and order | Showing your items |
| Tags: the tag names and colours you create, and which items carry them | Grouping and filtering |
| Sets: a name, whether the set is a plain count or a list of named slots, the target, and which of your items fills each slot | Tracking what is complete and what is missing |
| Your progress: points, level, streak, the badges you have earned and the record of the actions that earned them | Showing your progress in the app |
| Settings: whether the daily reminder is on and at what time, the accent theme you chose and which themes you have unlocked, and your view, sort and filter preferences | Running the app the way you set it up |
This data is written to your device’s private app storage. It is not transmitted to us or to anyone else, and we have no way to read it. There is no account, no login and no cloud sync — apart from loading advertisements, the app works completely offline. Uninstalling the app deletes all of it permanently.
One thing sits outside the app: if you have turned on Android’s own device backup, Android may include the app’s data in the backup it keeps in your Google account, so that your catalogue can be restored on a new phone. That backup is made and managed by Android and Google on your behalf; we cannot access it. You can turn device backup off in your phone’s backup settings.
You can add photos to an item in two ways. Choose from library opens Android’s photo picker: only the pictures you choose are handed to the app, and nothing else in your photo library is read. Take photo opens the camera; the app asks for camera permission at that moment, the first time you tap it, and not before. If you refuse, you can still add photos from your library.
Each photo you add is re-saved as a new copy in the app’s private storage, together with a thumbnail. The copies stay on your phone, are never uploaded, and are deleted when you remove the photo, delete the item, or uninstall the app. Your original pictures are left untouched wherever they were.
Your data leaves the app only when you send it somewhere yourself, from Settings → Data:
Files created for sharing are kept in the app’s private storage until Android clears them or you uninstall the app.
The app can send you one gentle reminder a day to add something to your archive. It is off until you turn it on in Settings → Reminders; on Android 13 and later your phone asks for permission to show notifications at that moment — not when you install the app. The reminder is skipped on days you have already catalogued something, and it is not sent at all on days when the app has nothing to nudge you about.
Notifications are scheduled locally on your phone. They are not push messages: nothing is sent from a server, and no one is told that a reminder fired or what you did with it. The notification text is the same every time and names nothing from your catalogue. Turning the reminder off in Settings → Reminders cancels it.
The app keeps a light record of your activity — items added, photos attached, sets completed — to award points, levels, a streak and badges. This record is stored with the rest of your data on your phone and is not sent anywhere. The optional accent themes can be unlocked by watching a rewarded advertisement, described below; nothing else in the app is tied to advertisements, and no feature is locked behind one.
Every item, photo, tag, set and collection can be deleted individually, and Settings → Data → Delete all data erases everything at once. Uninstalling the app, or clearing its storage from your device settings (Settings → Apps → CollectionLog → Storage → Clear data), removes everything, including photos and any backup file still in the cache.
Because we keep nothing anywhere else, that is a complete deletion — there is no copy on a server for us to remove, and nothing for you to request from us. Backups you exported yourself, and a device backup you have turned on in Android, are in the places you put them.
CollectionLog is free and is funded by advertising. We use Google AdMob to display:
Nothing you record in the app is ever sent to our advertising provider or used to select an advertisement. The part of the app that requests advertisements has no access to your catalogue.
To deliver and measure these advertisements, Google may collect and process:
| Data | Purpose |
|---|---|
| Device identifiers: the Android advertising ID and app set ID | Delivering advertisements (personalised ones only where you have consented), limiting how often you see the same one, measuring how advertisements perform, and preventing fraud |
| Device information (model, operating system, language, screen size) | Selecting an advertisement that fits your device |
| Approximate location, derived from your IP address | Serving region-appropriate advertisements and applying local law |
| Interaction data: app launches, taps, and views of advertisements | Measuring advertisement performance and preventing fraud |
| Diagnostic data about the app and the advertising library, such as launch time and responsiveness | Keeping advertisements working reliably |
This data is collected by Google, not by us. We only receive anonymous, aggregated reporting such as the total number of advertisements shown. Google’s handling of it is governed by its own policies:
If you are in the European Economic Area, the United Kingdom or Switzerland, the app shows a consent form the first time you open it, provided through Google’s User Messaging Platform. It asks whether Google and its advertising partners may store and access information on your device, such as the advertising ID, and use it for personalised advertising. You may refuse. If you refuse, you will still see advertisements, but they will not be personalised, and the app works exactly the same either way.
You can change your decision at any time from Settings → About → Ad privacy options. That option appears only where the consent form applies.
Everywhere in the world, you can limit advertising tracking through your device: Settings → Google → Ads (on some phones, Settings → Privacy → Ads), where you can reset or delete your advertising ID and opt out of ad personalisation.
| Permission | Why |
|---|---|
INTERNET, ACCESS_NETWORK_STATE | Downloading advertisements. Nothing else in the app uses the network |
AD_ID, ACCESS_ADSERVICES_AD_ID, ACCESS_ADSERVICES_ATTRIBUTION, ACCESS_ADSERVICES_TOPICS | Access to the advertising ID and to Android’s ad-measurement APIs, used by Google AdMob as described above. Added by the advertising library, not by the app itself |
CAMERA | Taking a photo of an item. Requested the first time you tap Take photo, not at install. Never used for anything else |
POST_NOTIFICATIONS | Showing the daily reminder. Requested the first time you turn the reminder on, not at install |
VIBRATE | Letting the reminder vibrate, if your phone’s notification settings call for it |
RECEIVE_BOOT_COMPLETED, WAKE_LOCK, FOREGROUND_SERVICE | Delivering the reminder reliably: re-arming it after your phone restarts, and letting scheduled work finish while the screen is off. Added by the notification and advertising libraries. They carry no data anywhere |
com.google.android.c2dm.permission.RECEIVE | Added by the notification library so that apps can receive push messages. CollectionLog never registers for push messages, so nothing is ever received through it |
READ_APP_BADGE and the launcher-badge permissions of several phone makers (Samsung, Huawei, OPPO, HTC, Sony and others) | Added by the notification library so that apps can show a number on their icon. CollectionLog never sets one |
BIND_GET_INSTALL_REFERRER_SERVICE | Added by a system library that can tell an app how it was installed. CollectionLog never reads it |
DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION | An internal permission the Android support library defines for the app’s own use. No other app can hold it |
That list is read out of the app’s build rather than written from memory, and is checked again against each release. The app does not request access to your files, contacts, microphone or location; photos reach it only through Android’s photo picker or the camera, and backups only through the share sheet and file picker.
There are none. The app contains no analytics library and no crash reporter, so we receive no usage statistics, no session data and no crash reports containing your information. What we can see is limited to the anonymous, aggregated figures Google Play and AdMob show every developer.
CollectionLog is not directed to children under the age of 13, and we do not knowingly collect personal information from children. If you believe a child has provided personal information through the app, please contact us and we will address it.
Because we hold no personal data about you, there is nothing for us to export or erase on request. To exercise rights relating to data collected for advertising — including access, erasure, or objection under the GDPR — please refer to Google’s Privacy Policy, which describes how to make such a request. You can delete all locally stored data at any time as described under Deleting your data above.
If this policy changes, the revised version will be published at this address with an updated date at the top. Significant changes affecting how data is handled will also be reflected in a new app release.
