Privacy Policy
1. Who we are
App Central is operated by Vishal Sharma, an independent developer. The site is reachable at app-central.in, and the creator's site is vishalsharma.cloud.
2. Information you enter, paste or upload
Apps ask for only what they need to work. Everything is processed in memory on our server to produce your result and is not written to a database or log. When you close the page, it is gone. We do not ask for email addresses, phone numbers or payment details. What each app handles:
Jyotish Darpan (astrology): name, date, time and place of birth. Used to compute your chart, then discarded. For AI readings only the computed facts (Moon sign, numbers, scores) and your first name are sent to the AI provider, never your full birth details.
Sketch Forge (sketch to code): the image you drop. It is held in memory, sent once to the AI provider to generate code, and discarded. It is never saved to disk.
Recall Vault (recordings): the audio or video file you upload, or the YouTube link you paste. The file is streamed to Google's Gemini Files API and deleted from our server immediately after upload. Google keeps the file for processing for up to 48 hours and then deletes it automatically; pressing "Forget" deletes it right away. A session reference lives only in our server's memory for up to 6 hours. Your questions and answers are not stored.
Refactor Lens (code review): the code you paste. It is sent once to the AI provider and discarded. Remove secrets, keys and customer data before pasting; we cannot see or filter them for you.
3. AI processing
When you press an AI button, our server sends the request described above to Google's Gemini API. Google processes it under its own API terms and, for the Files API, retains uploaded media for up to 48 hours. Your browser never connects to Google directly; only our server does, and our API key is never exposed to you. We ask the model for short answers and apply fair-use limits to keep every app free.
4. Usage logs for the developer tools
For Sketch Forge, Recall Vault and Refactor Lens we keep an audit log, because people can upload or paste material and we must be able to respond to legal requests and stop abuse. Before each use you confirm that the material contains no personal data of other people and no copyrighted content you lack rights to; that confirmation is recorded. Each log entry contains:
- date and time, which app and action (for example "vault / upload" or "refactor / analyse");
- your IP address, country code and browser user-agent string as supplied by Cloudflare;
- metadata of the material: file name, type and size, or code length and detected language, or the YouTube video ID;
- a SHA-256 fingerprint (hash) of the material, which lets us recognise the same file again but cannot be turned back into the content;
- for Recall Vault, the text of a typed question (up to 200 characters), and which preset was used; answers are not logged;
- the AI token count for the request.
The log never contains the image, recording or code itself. Entries are kept for 90 days and then deleted automatically. They are stored on our own server, accessible only to the operator, and are disclosed only when required by law or a valid legal request, or to investigate abuse of the Service.
5. Technical data
- IP address. Used in memory to apply fair-use limits on AI features (a small number of requests per hour), and recorded in the audit log above for the developer tools. For the astrology app it is not stored.
- Usage counters. We keep a daily count of AI requests overall. It contains numbers only, no personal data.
- Server logs. Standard, short-lived operational logs for keeping the site running.
6. Third-party services
- Cloudflare delivers the site and protects it from abuse. Cloudflare may process connection data under its privacy policy.
- Google Gemini API generates AI text and code, reads images, and listens to recordings as described above. Uploaded media passes through the Gemini Files API.
- YouTube videos you link are fetched by Google for the AI, not by us. Only public videos work.
- Open-Meteo geocoding converts a city name into coordinates when the city is not in our built-in list. Only the city name is sent.
- Google Fonts serves the typefaces used on the site.
7. Cookies and local storage
We do not set tracking or advertising cookies. An app may remember a small convenience setting (like your last tab) in your own browser's storage. It never leaves your device.
8. Children
The apps are for general audiences and offer cultural insight and personal reflection. We do not knowingly collect personal information from children under 13. Parents entering a child's birth details, for example to find a naming syllable, should know those details are processed and discarded as described above.
9. Your content and your rights
You keep all rights to the sketches, recordings and code you bring. We claim none, and we do not use them to train anything. Because we do not store them, there is usually nothing to access, correct or delete; for Recall Vault, "Forget" removes the AI copy on demand. You may ask to see or erase the audit-log entries linked to your IP address, subject to our legal obligations to keep them. If you believe we hold information about you, or have any question, contact us through the contact page and we will respond promptly.
10. Changes
We may update this policy as apps are added. The effective date at the top will change, and significant changes will be noted on the About page.
