Legal & Privacy

Last updated: 19 August 2026 · Applies to the AppVitamins fleet of free web tools and AI apps.

Privacy Policy

AppVitamins ("we", "us") builds free web tools and AI applications. We designed them to be privacy-first. This policy explains what data is and isn't handled when you use our tools.

What we do NOT collect

Most of our tools run entirely in your browser. We do not require an account, and we do not upload, store or transmit the content you put into a tool (text you type, files or images you choose, audio you record, or AI results) to our servers. That data stays on your device. Our in-browser AI tools download an AI model from a content-delivery network and run it locally — your input is never sent to us or any third party for processing.

Data stored on your device

Some tools save your preferences or history (for example saved invoices or a quiz streak) in your browser's local storage, on your device only. You can clear this at any time through your browser settings. It is never sent to us.

Analytics

Our hosting provider (here.now, on Cloudflare's network) records basic, aggregate page-view counts to help us understand which tools are used. This is high-level traffic data and is not used to identify you.

Advertising & cookies

Some pages may display advertising. Where we use Google AdSense or similar networks, those third parties may use cookies or device identifiers to serve and measure ads, including personalised ads where permitted. You can learn about and control this via Google Ads Settings and aboutads.info. See our Cookie Policy below. Where required, we ask for your consent before non-essential cookies are set.

Affiliate links

Some pages contain affiliate links. If you click one and make a purchase, we may earn a commission at no extra cost to you. This never affects what your tool does or the price you pay.

Children

Part of this site is made for children. Phonics Play, Spelling Bee Builder, Times Tables Trainer and Fractions Lab are learning tools written for young children and primary-school pupils. Those four pages carry no advertising of any kind — no ad tags, no ad network, no third-party scripts at all. They need no account and no sign-in, and nothing a child types, taps or scores is ever sent to a server — the tool runs entirely in the browser on your own device, and read-aloud uses the browser's own built-in voice. The only thing they keep is progress on that one device — a star or score count, a streak, a quiz best, and settings such as voice on/off, speaking speed and light/dark theme — held in your browser's local storage and gone as soon as you clear your browsing data.

We do not knowingly collect personal information from children, and these tools never ask a child for a name, an email address or any other identifying detail. Fractions Lab carries one optional "notify me" box addressed to parents, so we can tell them about new learning tools; it does nothing unless an adult chooses to fill it in, and submitting it simply opens our main site with that address carried over. Parents and guardians can reach us about anything — including having something looked at or removed — at support@appvitamins.com.

Your rights & contact

Because we don't collect personal data on our servers, there is generally nothing for us to access, correct or delete. For any privacy question — or anything else — contact us at support@appvitamins.com. We may update this policy; the date above reflects the latest version.

Terms of Use

By using AppVitamins tools you agree to these terms.

Use of the tools

Our tools are provided free for lawful personal and business use. You are responsible for the content you process and for how you use the results. Don't use the tools to break the law or infringe others' rights.

No warranty & no professional advice

The tools are provided "as is", without warranties of any kind. Calculators, AI outputs, transcriptions, translations and estimates may contain errors and are for general information only — they are not medical, legal, financial, tax or other professional advice. Verify anything important and consult a qualified professional where appropriate.

Limitation of liability

To the maximum extent permitted by law, we are not liable for any loss or damage arising from your use of, or inability to use, the tools.

Availability & changes

We may change, suspend or discontinue any tool at any time. We may update these terms; continued use means you accept the changes.

Cookie Policy

A cookie is a small file a website can store in your browser. Here's how cookies and similar storage are used across our tools.

Essential / functional

Local storage on your device may hold your in-tool preferences and history so a tool works the way you left it. This is functional and stays on your device.

Analytics

Aggregate, privacy-preserving page-view measurement by our host, as described above. No personal profile is built.

Advertising

This site uses Google AdSense. Google and its third-party vendors use cookies (including the Google DoubleClick DART cookie) and similar identifiers to serve ads based on your prior visits to this and other websites, and to measure them. You can opt out of personalised advertising at Google Ads Settings or www.aboutads.info. Other ad networks we may use are listed in our ads.txt. Where required by law, these are only set after you consent via our cookie banner, and you can withdraw consent at any time by clearing cookies or using the controls linked in the Privacy Policy.

Managing cookies

You can block or delete cookies in your browser settings. Blocking essential local storage may stop some tools from saving your work, but the tools will still run.
