Privacy notes

How UsefulKits handles information

Website, browser-app, contact, checkout and download information in one place.

Browser-app records generally stay on your device. UsefulKits does not use advertising trackers or third-party analytics scripts on this website.
01

This website

The website does not use advertising trackers or third-party analytics scripts. Its main text, images, videos and scripts are loaded from the same website.

02

Contact messages

When you use the contact form, the name, reply email address, subject and message you enter are sent through an email-delivery provider. A temporary hashed network identifier may be used briefly to limit repeated automated submissions. Contact details are used to answer the message and provide support.

03

Stripe checkout

UsefulKits uses Stripe for secure checkout and payment processing. Stripe processes payment information under its own privacy and payment policies. UsefulKits does not receive complete payment-card details.

04

Secure download delivery

For secure Stripe delivery, the site verifies the completed Checkout Session before releasing a purchased ZIP. It may record the session ID, payment status, amount, currency, download count and download times. Card details are not stored.

05

Browser-app data storage

Browser apps supplied through this site may store app records locally using standard HTML5 browser-storage technologies such as local storage, IndexedDB and browser cache. Unless an app states otherwise, locally stored records are not automatically synchronised between browsers or devices.

Clearing browser data, using private browsing, changing browsers, resetting a device or losing access to it may make locally stored records unavailable. Use any export or backup controls provided and keep backup files somewhere safe.

06

HTML5 browser-app safety

UsefulKits browser apps are supplied as HTML, CSS and JavaScript files that run inside a compatible modern browser. They do not require a native installer or administrator access. Modern browsers isolate web content within a browser sandbox, and an app cannot access unrelated files unless you choose a file or grant a browser permission.

No file format can guarantee complete safety. Use an up-to-date browser and open only copies obtained from the UsefulKits website.

07

Optional app functions

Some apps may provide receipt scanning, camera access, file import, file export or currency conversion. Browser permission is required for relevant device features. Review scanned, imported or converted values before saving them.

08

No financial advice

Budgeting, planning, reporting or record-keeping functions provided by UsefulKits apps are organisational tools. They do not provide financial, tax, legal or investment advice.
