What we actually store
There are exactly two places your data lives on our side, and both are Firestore collections in a Google Firebase project:
userCredits — your account ID, your credit balance, the totals added and used, and when the record was created and last changed.
creditTransactions — one line for every credit movement: the amount, whether it was added or used, a short description such as “Background remover — Zyv-Studio”, and a timestamp.
Your email address and display name are held by Firebase Authentication, which is how you sign in. If you used Google to sign in, Firebase also holds the basic profile Google returned.
That is the complete list. There is no analytics profile, no advertising identifier, and no record of which pages you looked at.
Images you edit
Three of the Zyv-Studio tools — the compressor, the converter and the resizer — run entirely inside your own browser. Those images never leave the machine you are sitting at. Nothing is uploaded, so there is nothing for us to keep.
The background remover and the upscaler need a model that is far too large to run in a browser, so those images are sent to our server. They are held in memory only — never written to disk, never copied to storage — processed, returned to you, and dropped when the response finishes. We could not retrieve one afterwards if you asked us to.
No image you send is used to train anything, by us or by anyone else.
Who else sees anything
Google (Firebase) — handles sign-in and stores the two credit collections above. Google's own privacy terms apply to that processing.
Groq and Novita — the assistant inside Zyv-Scan is an AI model run by these companies. When you ask it a question, a shortened summary of your hardware readings is sent so it can answer. It is only sent when you type something, and it does not include files, documents or anything personal beyond the hardware numbers.
Novita and OpenAI-compatible providers — Sellovo uses these to draft listing text from the product data it collected.
Nobody else. There are no advertising networks, no trackers, no data brokers, and nothing is sold or shared for marketing.
What stays in your browser
Two values are kept in your browser's local storage, and they never reach us:
zyvavo-theme — whether you chose light or dark, so the page does not flash the wrong one when it loads.
zyvavo-account — your initials, so the navigation can show your avatar without loading the whole authentication library on marketing pages.
Clearing your browser data removes both. Nothing breaks; you will simply get the default theme back.
The desktop apps
Zyv-Wallpapers sends nothing anywhere. It reads a video file you chose and plays it behind your desktop. It has no network code at all.
Zyv-Scan reads your hardware locally and shows you the results locally. The only thing that leaves your machine is the short summary described above, and only when you ask the assistant a question. If you never type anything, nothing is ever sent.
Getting your data, or getting rid of it
Write to support@zyvavo.com from the address on the account and ask for either:
A copy — we will send you everything the two collections hold about you, plus what Firebase Authentication has, in a readable file.
Deletion — we will delete the account, both collection records and the authentication entry. Any remaining credit balance goes with it and cannot be restored, so tell us if you would rather have a refund first.
One person handles these, so allow a few days rather than a few minutes. There is no charge and you do not have to give a reason.
Age
Zyvavo is not built for children and we do not knowingly hold data about anyone under 13. If you believe a child has created an account, write to us and we will remove it.
If this changes
The date at the top is when this page last changed. If something material changes — a new third party, a new kind of data — the change goes in here before it goes live, not after.
Written by the person who built the software, not copied from a template — so if something here does not match what actually happens, that is a bug and we want to hear about it: support@zyvavo.com.
