★★★★☆ Liza Dhar · Feb 10, 2022
Earlier my photos and videos are showing but suddenly neither my photos nor my videos are showing. Please give me solution of this problem.
★★★★★ M Parviz · Jul 6, 2024
Goodliest calculation Daffodils. Well mark Free@ship
★☆☆☆☆ Rob Smith · Aug 28, 2024
The calculator honest to God kept returning a mathematically incorrect result for a simple division equation (62k ÷ 52), as verified by multiple other calculator apps (rounds to 1192, *not* 1019). The app needs serious work. No excuse for a calculator returning wrong answers. Beware, do not trust or rely on this for anything important.
★☆☆☆☆ Mansuri Rano · Jul 22, 2023
I can't open this app. Please do something I really need to open it because my photos and videos are very important
★☆☆☆☆ Aravindhan · Nov 16, 2022

Description by Green Water Written by the developer, not by AppBrain. Click to read.
Your calculator. Your private vault.

Calculator+ combines an everyday calculator with a passcode-protected vault for your personal photos and videos. Keep your media organized in albums, and export or share copies whenever you choose.

PRIVATE PHOTOS AND VIDEOS

• Import photos and videos from your gallery
• Take a new photo and add it to your vault
• Organize your media into albums
• View, export, share, or delete files in the vault
• Keep your gallery originals, or choose to delete them after a successful import

CALCULATOR ACCESS

Set up your vault passcode when you first use the app. To open the vault, enter your passcode on the calculator keypad and tap %. Leave the vault to return to the calculator for everyday calculations.

Calculator+ does not hide its app icon. Importing media does not automatically remove the original files from your gallery.

CLOUD BACKUP

Sign in with Google to use account-based cloud features. Back up your media and restore it when you need it. Some features may require a paid membership.

PRIVACY AND CONTROL

Vault files are stored in the app's private storage. Media content stays on your device unless you use a feature that transfers it, such as cloud backup, export, sharing, or a feedback attachment.

Account and device services, advertising, and analytics may process other information as explained in our Privacy Policy. Device registration sends your vault PIN and device information to our backend over HTTPS. We do not use the contents of your private photos or videos for advertising or analytics.

The free version may display ads. Use "Manage ad privacy" in settings to review your advertising choices when that option is available.

KEEP YOUR MEDIA SAFE

Remember your vault passcode and protect access to your device and Google account. If you forget your passcode, you may lose access to your vault.

Uninstalling the app, clearing app data, or resetting your device can delete local vault files. Before uninstalling, resetting, or changing devices, make sure you have a completed cloud backup or exported copies of the files you want to keep.

ACCOUNT AND DATA DELETION

To request deletion of your Calculator+ account and associated server data, visit:
https://calvault.alwaysgreenwater.info/delete-account

Uninstalling the app does not automatically delete your account or cloud backups. For deletion assistance, email greenwateralways@gmail.com.
