Privacy Policy

Effective 14 September 2026 · Applies to Sharpen for Android (com.sharpen.daily)

Sharpen has no accounts, no sign-up, and no login. It does not ask for your name, your email, your phone number or your contacts, and it has no server that stores anything about you.

Sharpen is published by Northway Dev Team (“we”, “us”), which is the party responsible for it. You can reach us at gabrerllehuffmanhuffman@gmail.com about anything on this page.

The short version

1. What the app stores, and where

On your device, and nowhere else:

• Which puzzles you have played, your answers, your times and your scores.
• Your streak, and how many weekly freezes you have left.
• Your settings: language, difficulty, reminder time, haptics, sound, music.
• The puzzles themselves, so the app works with no connection.

None of this is uploaded. There is no backup to our servers because there are no servers of ours beyond the one that hands out puzzles, and that one only ever sends puzzle files — there is nothing of yours for it to receive.

Uninstalling the app deletes all of it. There is nothing to request, export or erase from us, because we never had it.

If you have Android's own backup turned on, Android may include some of this in your Google account backup. That is Google's service operating under Google's terms, not ours.

2. Downloading puzzles

The app fetches puzzles over HTTPS from our content delivery network. The request contains no identifier of any kind — no account, no device ID, no advertising ID. It does, unavoidably, reveal your IP address and approximate location to the network that serves the file, which is true of loading any web page. Our CDN provider keeps standard server logs under their own retention policy.

We do not log which puzzles your device asked for in any form tied to you, and there is nothing in the request that would let us.

3. Ads

Ads are served by Google AdMob. To do that, Google receives:

• A resettable advertising ID — an identifier you can reset or delete at any time in Android's Settings → Privacy → Ads.
• Device and connection information such as device model, operating system version, language, coarse location derived from IP, and the app you are using.
• Whether you interacted with an ad.
• An app set ID — a second identifier, also Google's rather than ours, which is shared across apps from the same developer on your device and is reset when you uninstall them all.
• Performance and diagnostic information about the advertising SDK's own behaviour, such as how long it took to start and whether it stopped responding.

Google uses this to select and measure ads, and to limit how often you see the same one. What Google does with it is governed by Google's Privacy Policy and how Google uses data from apps that use its services.

Your choice about personalised ads

Where the law requires it — broadly the EEA, the UK and Switzerland — the app asks before it requests a single ad, through Google's certified consent platform. That question comes first and gates everything after it: if consent is not given, the app does not start the advertising SDK at all, and no ad is requested. Where that choice applies you can change it at any time from Settings → Ad privacy choices in the app.

Outside those regions you can still stop personalised advertising by resetting or deleting your advertising ID in Android's own settings.

We do not sell your data. We could not: we never receive it. The only thing we see is an aggregate count of impressions and revenue in the AdMob console, with no identifiers in it.

4. What Sharpen does not do

• No account, no sign-up, no login, and no server of ours that stores anything about you.
• No asking for your name, your email address, your phone number or your contacts.
• No identifier of any kind in the puzzle request — no account, no device ID, no advertising ID.
• No log, in any form tied to you, of which puzzles your device asked for.
• No reminder sent from a server, and nothing about your reminder schedule leaving the device.
• No selling of your data to anyone. We could not: we never receive it.
• No location, camera, microphone, contacts or storage permission, and no ability to read any of those.

5. Notifications

If you turn on the daily reminder, the app schedules it locally on your device using Android's own work scheduler. No reminder is sent from a server, nothing about your schedule leaves the device, and turning it off cancels it immediately.

6. Children

Sharpen is a general-audience word and trivia app and is not directed at children. We do not knowingly collect anything from anyone, of any age — see above for why there is nothing to collect. The ad-supported build serves ads through AdMob, which is why it will not be listed as a children's app.

7. Permissions, and why each exists

The app asks for no location permission, no camera, no microphone, no contacts and no storage access, and it cannot read any of those.

8. Your data, and deleting it

Everything the app knows about you is on your device, listed in section 1. Uninstalling the app deletes all of it. There is nothing to request, export or erase from us, because we never had it.

Data-protection rights — to see a copy, correct it, or have it deleted — are rights against whoever holds the data. We hold none of yours, so there is nothing here to show you, correct or erase. Section 1 is why.

The advertising data described in section 3 is held by Google, not by us, and Google's policies — linked in that section — describe what Google does with it. Where the law requires consent before ads may use your data, that consent is the one you give or decline in Google's consent form, and you can change it at any time from Settings → Ad privacy choices. You can also reset or delete your advertising ID in Android's Settings → Privacy → Ads, on any device and in any region.

9. Changes

If this policy changes in a way that affects what leaves your device, the app's Settings → Privacy text changes with it, and the change is described here with a new effective date. A version of this document's history is kept in the project's repository.
