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.
Tools identified as browser-only process working content on your device and may store preferences there. Connected features send information to the selected service. The owner-operated YouTube publisher is described separately below; its content does not stay entirely on-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.
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.
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.
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.
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.
For privacy questions or requests to access, correct or delete information we hold, contact support@appvitamins.com. Options depend on the feature: clearing browser storage differs from revoking the YouTube publisher or asking an external provider to remove its records.
AppVitamins is operated by Tim Munnik. Our music website is music.appvitamins.com. Music Creations YouTube Publisher is our local desktop tool for uploading approved music videos, organising YouTube playlists and managing lyric captions. It uses YouTube API Services.
The publisher is currently used by the owner for the owner's channel. Visitors to the music website are not asked to connect a Google Account. The desktop publisher's data practices are described below; they differ from those of our browser-only tools.
An authorised channel owner connects through Google's consent screen. We do not ask for or store a Google password. Google provides credentials that let the publisher carry out the authorised work and renew its connection without repeated sign-in.
The requested permission is youtube.force-ssl. Google describes it as permission to see, edit and permanently delete YouTube videos, ratings, comments and captions. We use it to upload videos, manage playlists and publish or revise captions. The current publisher does not implement video, rating, comment or caption deletion features. The requested scope is broader than the actions we implement; Google's narrower upload permission does not cover caption management.
The channel owner controls the intended title, description, audience, visibility, playlist and caption content. Connecting an account is not an instruction to publish every local file. The publisher does not autonomously make unlisted videos public.
The publisher handles:
This integration does not request Gmail, Google Drive or Google Contacts access, and it is not designed to collect viewers' private information.
We use this information to perform the requested publishing work, avoid duplicate uploads, check the correct channel and visibility, and verify caption accuracy and timing.
The publisher runs on the authorised operator's Windows computer. OAuth tokens are stored there using Windows-protected encryption. Client configuration is kept separately from public website files. Local release records may include identifiers, settings, file checksums and quality-check results. We do not upload the publisher's OAuth tokens to the public music website or its hosting provider. Security protections reduce risk; no system can promise absolute security.
Google/YouTube receives authorised uploads and API requests. Our website hosting providers, here.now and Cloudflare, deliver the public music page and may process ordinary request information needed to operate and protect it. The public page does not provide the publisher's account connection.
With the channel owner's approval, OpenAI Codex can assist with publishing and checks. Relevant channel/video identifiers, metadata, caption text or diagnostic results may be included in the assistant's tool outputs or conversation for that task. OAuth access and refresh tokens and Google passwords are not supplied as conversation content. This is a data transfer to the AI service; it is not a wholly on-device workflow. Provider processing and international transfers are subject to the applicable service terms and OpenAI privacy information.
We use Google API data for authorised publishing and checking. We do not sell it or use it for advertising or credit decisions. We are reviewing the AI-provider account settings and retention arrangements before expanding this integration; no provider-wide no-training or deletion guarantee is made here.
The Google API Services User Data Policy, including its Limited Use requirements, governs this integration. Google verification is pending. This notice describes the present implementation and does not certify compliance or verification approval.
The owner-operated publisher currently keeps API-derived release records and diagnostic evidence locally. Automated expiry, refresh and deletion controls are under development; a fixed automatic deletion schedule is not yet enforced. OAuth tokens are retained for the authorised connection until revoked or removed. For a privacy or deletion request, contact the operator below. We must complete and test the retention and deletion controls before claiming that this integration is ready for Google verification.
Original creative files created independently of the API are separate from cached Google data. They are not automatically erased by revoking an account connection. API-downloaded copies must be handled separately from original creative files.
Deleting data held by the publisher does not delete videos, playlists or other content already on YouTube. Manage those through YouTube Studio. It also does not automatically remove a conversation held by a separate AI service; we must account for any such Google-data copies when handling deletion and retention requests.
You can revoke the connection in Google Account third-party access settings. The publisher does not yet provide its own disconnect-and-cleanup command. Revocation blocks further authorised API work but does not itself erase existing local records or AI-service conversations. Contact the operator for a deletion request. After revocation, publishing requires a new authorisation.
For access, correction, deletion or privacy questions, contact support@appvitamins.com and identify the publisher and channel concerned. Do not send passwords, authentication codes or tokens. We may ask for a safe way to confirm that the request concerns your account.
Google/YouTube's separate processing is described in the Google Privacy Policy. We will update this notice when the publisher's data practices change and seek fresh consent where a change requires it.
