Privacy policy

Short version: we hold your email, your credit balance and a log of what you spent it on. Images you edit never leave your device. Nothing is sold, and nothing trains a model.

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

Every Zyv-Studio tool runs entirely inside your own browser — the compressor, the converter and the resizer, and the background remover and the upscaler too. Your 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 use AI models: IS-Net for cutting out and Real-ESRGAN for upscaling. The first time you use one, your browser downloads that model from zyvavo.com and keeps it, so it is not downloaded again. The model then runs on your device's graphics chip, or its processor if there is no usable one.

What does reach us is the charge: when a job finishes, your browser asks our server to take its credits, and the record says which tool, how many credits and when — never the picture.

No image you edit 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.

Novita — the project assistant on the services pages sends your conversation to an AI model Novita runs, so it can reply. We do not store or log what you write; our server records only how many messages there were and how long the answer took. Your brief reaches Zyvavo only if you choose to send it yourself, on WhatsApp or by email.

Novita — the Prompt Enhancer sends the text you type to an AI model Novita runs, once, to write the improved prompt. We do not store it or log it; our server records only its length and how long the answer took. Novita's own terms apply to that processing.

If you use the Prompt Enhancer without signing in, our server counts today's free tries against your IP address. That count lives in memory only, is never written to disk, and is forgotten when the day changes.

Fonts are served from our own domain. Your browser does not contact Google Fonts or anyone else to draw text.

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.

Three more sit in session storage and vanish when you close the tab — they only help the intro and the sign-in flow behave. The cookie policy lists each one.

Clearing your browser data removes all of them. 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.
