Privacy
Last updated 22 August 2026. Covers handeware.com, mahjong.handeware.com, and the Handeware apps — Sift, Chartra and Mahjong Solitaire Otto. We have no accounts, no logins and no analytics, and we run no server that any of our apps talk to.
The apps
Sift and Chartra run entirely on your device. There is no account to make, no sign-in, and no server of ours for them to contact. Your photos, documents and contacts are read on the phone and are never transmitted to us — we could not retrieve them if we were asked to, because no copy exists anywhere but your device.
- Photos. Sift reads your library to find duplicates, blurry shots, screenshots and large video. Analysis happens on the device. Nothing is uploaded.
- Documents. Chartra scans, reads, signs and exports on the device. Text recognition is local.
- Contacts. Sift checks for duplicates only if you tap the button that asks for access. Nothing leaves the phone.
- What Sift remembers. A small model trained on your own swipes, and a record of past scans. Both live on the device and both can be erased in Settings inside the app.
- Purchases. Handled by Apple. We never see your payment details, and your purchase is tied to your Apple ID rather than to any record we hold.
You can verify all of this: run a scan with the phone in airplane mode. It completes normally, because nothing needed a network.
Ads inside the apps
Sift and Chartra offer a short ad in exchange for extra free use. Those ads are served by Google AdMob, which may use an advertising identifier and coarse device information to select and measure them. That data goes to Google, not to us, and it concerns the ad — never your photos, documents or contacts, which the ad software has no access to.
iOS asks your permission before any app can track you across other companies’ apps, and in the EEA, UK and Switzerland you also get a consent prompt. Declining either changes nothing about what the app can do; you simply see non-personalised ads. Paying to remove ads removes the ad software’s involvement entirely.
This website
handeware.com serves no ads and runs no analytics. We do not set cookies, and we do not know who visits. Our host keeps standard server logs, as every web host does.
Your saved games
Mahjong stores your progress in your browser’s
localStorage. It never leaves your device — the game
makes no network requests while you play. Clearing your browsing data
deletes it, and we cannot recover it.
Sugar Block Works keeps your score, coins and unlocked crew on the device itself. There is no account and no server of ours to sign in to. The game does reach the network for the ads described above, and for Game Center leaderboards if you choose to use them — Game Center is Apple’s, and what it stores is covered by Apple’s privacy policy, not ours. Deleting the app deletes your progress, and we cannot recover it.
Children
Our apps are not directed at children under 13 and we do not knowingly collect anything from them. Since we collect nothing from anyone, there is nothing to delete on request — but write to us with any concern and a person will answer.
Your rights
GDPR, CCPA and similar laws give you the right to see, correct and delete data a company holds about you. We hold none. There is no account, no profile and no record of you in our possession, so there is nothing for us to produce or erase. Data held on your own device is removed by erasing it in the app, or by deleting the app.
