This Privacy Policy describes how LogicGateGames LLC handles information when you use QuiNotes. By using the App you agree to the practices described here.
1. Your Notes Stay On Your Device
QuiNotes keeps your notes in a private database on your phone. There is no account, no sign-in, and no sync. We operate no servers for your content, so there is nowhere for your notes to be sent.
The App does use the internet, and we will not pretend otherwise: it is required to fetch advertisements, to talk to Google Play about purchases, and to send a crash report if the App crashes. Your notes are not part of any of these.
2. Information We Collect
The only thing we receive is a crash report. We have no analytics and no account system. If the App crashes, a crash report is sent (see Firebase Crashlytics below). We never see your notes, their titles, your photographs, or your voice recordings.
The services we use do collect data inside the App, and we list them here because "we have no server" is not an exemption:
- Google AdMob - Displays ads. Collects the Advertising ID (a resettable device identifier), ad interaction data, device model, OS version, and approximate location derived from your IP address. You can reset this ID in your device settings.
- Google Play Billing - Handles purchases. Google tells the App which items you own. We never see your card details, and no payment information reaches us.
- Firebase Crashlytics - If the App crashes, Crashlytics sends a crash report so we can fix the problem. A report contains the error's technical details (stack trace), device model, Android version, app version, the type of build and the name of the app store it was installed from, and a random Crashlytics installation ID. It never includes your content, such as your notes, and it contains no name, email or advertising ID. Reports are processed by Google and kept for up to 90 days. We do not sell or share them.
Nothing from a note - not its text, its title, its photographs, its recordings, nor whether it is locked - is included in any ad request, purchase check, or crash report.
3. What Is Stored On Your Device
- Your notes, checklists, categories, tags, and the paper each note wears.
- Photographs and voice recordings you attach, saved as the App's own private copies.
- Any reminder you set, and when it should next arrive.
- Your preferences, and whether you have made the one in-app purchase.
This data is readable only by the App. It is not included in Android's cloud backup, and it is removed when you uninstall QuiNotes.
4. Photographs, Recordings And Files
When you attach a photograph, QuiNotes asks Android's photo picker for that single image. It does not request access to your photo library, so it cannot see any picture you have not chosen.
The App saves its own copy inside its private storage, so your note still shows the picture if you later move or delete the original. Voice recordings are made only while you are holding the recorder open, and are written to the same private storage. Neither is ever transmitted.
You can also attach any other file — a PDF, a receipt, a document. As with a photograph, you choose the single file and QuiNotes copies it into its own private storage rather than keeping a link to wherever it came from.
There is one thing worth knowing about those files. QuiNotes can display a photograph and play a recording itself, so it never hands either to another app. It cannot display a PDF or a spreadsheet, so when you tap one to open it, the App passes that single file to whatever you choose to open it with, for as long as that app is handling it. Apart from the backups, exports and printing you start yourself (section 7), this is the only circumstance in which anything from your notes leaves QuiNotes, and it happens only when you tap the file yourself.
5. Reading Text In Your Photographs
So that search can find words that appear inside a picture — the amount on a receipt, a name on a card — QuiNotes reads the text in each photograph you attach.
This happens entirely on your device. The recognition models are built into the App itself; nothing is uploaded, nothing is downloaded, and it needs no connection. Neither the picture nor the text read from it is sent to Google or to us: it never leaves your phone and no one but you ever sees the result.
The words found are stored with the note, in the same private database as the note itself, purely so that searching can match them. Because they are stored with the note, they are included in a backup or export you create, and they are deleted when you delete the note or uninstall the App.
Recognition is imperfect and is only ever used to help search find a note. QuiNotes does not interpret what a picture is of, does not recognise faces, and does not use anything it reads for any other purpose.
6. Locked Notes
You can lock any note, free of charge. The lock uses your device's own credential - fingerprint, face, PIN or pattern - checked by Android. QuiNotes never receives your fingerprint or face data; it asks Android whether the check passed and is told only yes or no. We store no PIN, password, or hash of our own.
A locked note's text is never previewed where someone else might see it: a notification for it says only that a note is locked, the home-screen widget shows only "Locked", and search never looks inside it. Search can find a locked note only by its title or a tag, so its title is shown in the results when the title or a tag matches; its text, checklist and photograph words are never searched or shown.
Please note that a lock is not encryption. A backup file you create yourself contains your locked notes in readable form, and the App tells you so before it writes one.
7. Backups And Exports
QuiNotes can write your notes to a file, and this only ever happens when you ask for it. Android asks you to choose where the file goes. Once saved, that file is outside the App and under your control - if you place it somewhere that syncs to a cloud service, that service's own privacy terms apply to it. QuiNotes itself uploads nothing and has no access to any cloud account.
A backup is a .zip file containing your notes and their attached photographs, recordings and files; an export is your notes as plain text, Markdown or PDF. You can also print your notes, in which case Android's print service passes them to the printer or print service you choose.
8. Permissions
- Internet and network state - Used to fetch advertisements, to reach Google Play for purchases, and to send a crash report if the App crashes. Never used to send your notes.
- Notifications - Used to show the reminders you set. If you decline, the App works normally and simply does not notify you.
- Alarms and reminders - Lets a reminder arrive at the time you asked for rather than whenever the system next chooses to wake the App. Optional; without it reminders still arrive, just less precisely.
- Run at startup - Used solely to restore your existing reminders after the device restarts, because Android clears scheduled alarms on reboot.
- Microphone - Used only while you are recording a voice memo into a note. Nothing is recorded in the background, and the recording stays on your device.
- Vibration - Used for brief haptic feedback.
- Biometrics - Used only when you lock or open a locked note, so Android can check your fingerprint, face or screen lock (see section 6).
- Advertising ID - Added by Google AdMob so it can read the Advertising ID described in section 2.
Apart from these, and routine permissions the Google libraries add for their own background work and purchases, QuiNotes requests no other permissions. In particular it does not request storage access, location, contacts, or your photo library.
9. Advertising
Ads are shown via Google AdMob. You can opt out of personalised ads in device Settings under Google - Ads. If you are in the European Economic Area, the UK, or Switzerland, you will be asked for your advertising consent choices when you first open the App, and you can change them at any time from Settings > Manage ad preferences in the App.
Ads can be removed permanently with a single one-time purchase, "Unlock everything", which also unlocks the locked papers, the paper designer and rich-text formatting. There is no subscription.
10. Children
QuiNotes is not directed at children. The App is not marked as child-directed for advertising purposes, and we collect no personal information from anyone ourselves.
11. Your Rights
We hold no personal data about you, so there is nothing for us to give you a copy of, correct, or erase. The only thing that reaches us is a crash report if the App crashes; it contains no name, email or advertising ID and is deleted automatically after 90 days. Everything else is on your device: you can export or back it up at any time from within the App, and uninstalling removes all of it. To reset the advertising identifier, use your device's own Google settings.
12. Changes To This Policy
We may revise this policy. The date above reflects the latest version, and any material change will be reflected in the App before it takes effect.
