Privacy Policy — Smart Suggest

Last updated: 18 August 2026 · Android app com.lukecao.suggest

Smart Suggest is an Android home-screen widget that suggests apps you are likely to open next. This policy describes what the app does with data. It is written to match what the code actually does; where a claim is narrower than you might expect, that is deliberate.

What the app reads on your device

To rank apps it reads, with your permission in each case:

• App usage history (usage access) — which apps were opened and when. This is the permission the app cannot work without.
• Calendar (optional) — event times, and whether an event names an app you have installed.
• Notifications (optional) — that a notification arrived, and from which app.
• WiFi network identity (optional) — used only to tell "the same network as before" from "a different one".

Each optional signal has a switch in the app's settings and is off until you turn it on.

What is stored, and for how long

Stored in the app's private storage, which other apps cannot read:

• App sessions — which app, and when. Pruned to the last 21 days.
• WiFi network names, hashed (SHA-256, truncated). The app only ever compares two hashes for equality. It cannot recover the network name from what it stores, and neither can anybody reading the database.
• Calendar-derived time windows, and a package name if an event names an installed app. No titles, descriptions, locations or attendees are stored. They are examined in memory to look for a meeting link and then discarded.
• Notification records: a package name and a timestamp only. No titles, no text, no senders, no content of any kind, and only for apps that appear in your launcher.
• Counts of which suggestions the app itself showed, so it can tell a suggestion you ignored from one you never saw.

This data is excluded from Android cloud backup and from device-to-device transfer, so it does not follow you to a new phone. A new phone starts with an empty history.

Uninstalling the app deletes all of it. There is no copy anywhere else.

Location

This version of the app does not request location and does not receive it. The location-based ranking was built and measured, and then deliberately left out of the release. If that ever changes, it will require a new permission request that you would have to grant, and this policy will be updated first.

Advertising

The free version shows a single ad bar at the bottom of the app's own settings screen. It never appears on the widget or over your home screen.

Ads are served by Google AdMob using the Google Mobile Ads SDK. Google's SDK collects and shares, for advertising, analytics and fraud-prevention purposes:

• your device's IP address, which may be used to estimate its general location;
• the advertising ID and similar device or account identifiers;
• interactions with the ad — that the app launched, taps, video views;
• diagnostic information about app and SDK performance.

That collection is Google's, under Google's Privacy Policy, and it is described at Google's AdMob data disclosure page. Data is encrypted in transit.

None of the app's own data is sent with the ad request. Your app history, calendar information, notification records and WiFi hashes are not shared with Google, with any advertiser, or with anyone else. The advertising code in this app cannot reach the ranking data at all — the two are kept in separate parts of the app and this is verified against the compiled build rather than merely intended.

You can reset or limit your advertising ID at any time in Settings → Google → Ads on your phone.

If you are in the EEA, the UK or Switzerland

Before requesting a single ad, the app asks for consent using Google's User Messaging Platform, and shows the consent form when the law requires it. You can change your choices later from the same dialog's privacy-options entry point. Declining does not stop the app working; the widget and the ranking behave the same either way.

Removing ads

A single one-off in-app purchase removes the ad bar permanently. The payment is handled by Google Play; the app never sees your card or payment details. All the app receives is the answer to has this person paid. Google Play's handling of the transaction is covered by Google's own privacy policy.

If a purchase cannot be confirmed — because the network is down, for example — the app treats an unanswered question as "still paid" rather than putting the ads back. Ads only return if Google Play positively says the purchase is gone, such as after a refund.

Children

Smart Suggest is not directed at children and is not intended for anyone under 13.

Analytics

The app contains no analytics of its own. Nothing counts your launches or reports your behaviour to the developer. The only diagnostic information that leaves the device is what the Google Mobile Ads SDK sends, described above.

Your choices

• Turn any optional signal off in the app's settings; the app stops reading that source.
• Revoke usage access, calendar or notification access in Android's own settings at any time. The app degrades rather than breaks.
• Hide any app you never want suggested.
• Uninstall, which deletes everything the app has stored.

Changes

If this policy changes, the date at the top changes with it. Material changes to what the app collects will be described in the app's release notes.
