Zen Cleaner · Privacy Notice

What we hold, and why.

Zen Cleaner touches five kinds of data. Rather than one long list, this notice gives each kind its own card and puts the same five questions to it every time: what it is, why we need it, which legal basis applies, who else receives it, and how long it stays.

01Who is accountable

Korvianex FZE, the controller

Korvianex FZE builds Zen Cleaner and ships it on the App Store. We are incorporated in the United Arab Emirates, and we are the party that determines what personal data the app touches and to what end. Data-protection law, the GDPR included, calls that role the “controller”.

Zen Cleaner exists for one task: hunting down duplicate and look-alike photos, extra screenshots, repeated videos and doubled-up contact cards on an iPhone or iPad, then letting you sweep them away so storage frees up. No account, no sign-up, no login screen.

02On-device by design

The library never leaves the phone

Matching is done by your iPhone’s own chip. Pictures, clips and address-book entries are not uploaded, neither to Korvianex nor to a single partner of ours.

  • Permission first. Until you answer Apple’s Photos or Contacts dialog with a yes, Zen Cleaner sees nothing. Full library, a hand-picked selection, or zero access: each is your call.
  • You press the button. The app never deletes on its own initiative; every removal needs your tap. Photos and videos you discard go to iOS’s “Recently Deleted” album and can be pulled back from there for a limited time.
  • Revoke whenever. Adjust or remove access in Settings › Zen Cleaner, or via Settings › Privacy & Security and then Photos or Contacts.
03The inventory

Data, category by category

Five buckets hold everything Zen Cleaner deals with. Every card runs through an identical five-row grid, which makes comparing them easy.

Library data

Read on the device only
What
Camera-roll items (photos, screenshots, videos) and address-book contacts held locally, plus similarity scores Zen Cleaner derives while comparing them.
Why
Spotting doubles and near-doubles, then laying them out so you pick what goes.
Legal basis
The contract between us (running the feature you launched the app for), on top of the iOS permission you granted.
Who receives it
Nobody. Content and analysis both stay inside Zen Cleaner, on your hardware.
How long
Zero time on our side, since we never hold it. Results sit on the device and disappear when the app is uninstalled.

Device data

Technical details, usage events, crashes
What
Hardware model, iOS build, Zen Cleaner version, interface language, region, time zone, IP address, network carrier. In-app events, for instance which screens get opened, which tools get used and the numbers a scan produced (item counts and megabytes, never a file). Crash traces and performance diagnostics.
Why
Keeping the app running, stable and safe; catching fraud; seeing which tools people actually find useful; and trying out screen or setting variants with Firebase Remote Config.
Legal basis
Contract, for whatever is needed to deliver the service. Legitimate interests, for reliability, security and product improvement.
Who receives it
Google Firebase (Analytics, Crashlytics and Remote Config) and AppsFlyer, each bound to act only on our instructions.
How long
Each provider’s configured retention window; once it lapses, records are erased or folded into aggregate statistics.

Purchase data

Reported to us by Apple
What
Plan selected, trial status, each renewal or cancellation, transaction IDs, amount charged and its currency. All of this reaches us from Apple, which runs the actual payment, so your card number and billing details stay with Apple.
Why
Switching Premium on, verifying it is still active, restoring it on a new device, flagging fraud, bookkeeping, and supplying Apple with consumption information when it asks about a refund claim.
Legal basis
Contract. Legitimate interests (fraud control; handling refund questions). Legal obligation (tax and accounting).
Who receives it
Apple. Apphud, our subscription-status service. AppsFlyer, Meta and Google Ads, so a purchase can be credited to the campaign behind it (see the identifiers card for how consent fits in).
How long
Through the life of your subscription, then for however many years tax and bookkeeping statutes demand.

Identifiers

Install IDs, ad ID, attribution
What
IDFV (Identifier for Vendor). Install or instance IDs that partner SDKs generate. A push token, if notifications are on. IDFA (Identifier for Advertisers), solely when you choose “Allow” in Apple’s App Tracking Transparency dialog. Attribution details, meaning which campaign or source led to your install.
Why
Recognising the same installation across sessions, linking a purchase to it, sending notifications, plus measuring ads and building ad audiences on Meta and Google.
Legal basis
Legitimate interests cover IDFV and SDK IDs used for operation and analytics. Consent given in the ATT dialog covers IDFA-based measurement and audiences; consent given in iOS’s notification dialog covers push. Say no to tracking and we get just aggregated, privacy-preserving campaign figures through Apple’s SKAdNetwork and AdAttributionKit.
Who receives it
AppsFlyer, Google Firebase (Cloud Messaging among its parts), Meta, Google Ads, Apphud, and Apple, which delivers push messages.
How long
While Zen Cleaner remains installed and inside every partner’s own retention period. Flip tracking off and the advertising ID stops flowing straight away.

Support messages

Only what you choose to send
What
Whatever arrives at hello@korvianex.ink from you: sender address, a name if you sign with one, the text, any screenshots attached, and any device details you volunteer.
Why
Replying, getting the issue fixed, and keeping a note of what was settled.
Legal basis
Contract, when your question concerns the app or a subscription; legitimate interests for everything else.
Who receives it
Just the Korvianex people working on your ticket.
How long
Till the issue is closed, then a sensible grace period in case a follow-up comes in.

Deliberately out of scope

Three things Zen Cleaner simply does not gather:

  • Photo, video or contact content
  • Precise location
  • Payment card data
04The ledger

Purpose by purpose, basis by basis

Same information as the cards, flipped around: here the starting point is what we do, not what we collect.

Running Zen Cleaner and unlocking Premium
Contract
Stability, security and anti-fraud work
Legitimate interests
Analytics, plus A/B experiments via Firebase Remote Config
Legitimate interests
Ad measurement and audience building with Meta and Google
Consent in the ATT dialog. No consent: aggregated figures only, via SKAdNetwork and AdAttributionKit
Push notifications
Consent in iOS’s notification dialog
Support
Contract, or else legitimate interests
Replying to Apple’s consumption-information requests tied to refunds
Legitimate interests
Tax, accounting and other statutory duties; lawful requests from authorities
Legal obligation

Legitimate interests are only relied on after balancing them against your privacy, and you can object to that processing whenever you like (see your rights). Consent can be pulled back just as simply as it was given.

Where ad measurement is concerned, Meta and Google can also act as independent controllers, governed by their own privacy policies.

Rare, non-routine disclosures

  • Public authorities, if statute, a court or a regulator compels us.
  • A purchaser or successor, should Korvianex or Zen Cleaner change hands through a merger, acquisition or asset sale.
  • Anybody else, strictly with your agreement or at your request.

Selling personal data is not part of our business. We do not do it.

06Your switches

Tracking and ad controls

  • ATT dialog. Answer “Ask App Not to Track” and the IDFA stays out of reach for us and every partner.
  • Second thoughts? Toggle it in Settings › Privacy & Security › Tracking.
  • Apple’s ad platform has its own personalisation switch in Settings › Privacy & Security › Apple Advertising.
  • Meta and Google offer controls at Meta ad preferences and My Ad Center. Cross-industry options: AppChoices and the NAI opt-out page.

“Do Not Track” is a browser feature; Zen Cleaner is a native app and does not react to that signal.

07Across borders

Data crossing borders

Some of our people and several vendors sit in other countries, the United States among them. For personal data originating in the EEA, Switzerland or the UK, one of these safeguards applies:

  • an adequacy decision covers the recipient’s country, for example the EU–U.S. Data Privacy Framework where the recipient holds certification; or
  • Standard Contractual Clauses issued by the European Commission are signed (with the UK addendum where needed).

Ask by email and we will send you the relevant safeguard document.

08Keeping and protecting

Retention and security

Rule of thumb: data lives exactly as long as its purpose does. Concretely:

  • support threads, until resolved, then a sensible grace period;
  • analytics and diagnostic records, per each vendor’s configured window;
  • purchase records, as long as tax and accounting statutes require.

Data the app sends to our partners travels over TLS encryption. Internally, access is least-privilege: a team member sees only what their job needs. Vendors are chosen partly for their security record. Still, no setup is bulletproof; spot something odd and we want to hear about it.

09Your rights

What you can ask of us

Under the GDPR, the UK GDPR and similar laws, you are entitled to:

  • access: find out what we hold on you and get a copy;
  • rectification: get wrong details fixed;
  • erasure: have data wiped;
  • restriction or objection: limit processing, or oppose it, legitimate-interest processing included;
  • portability: take data you gave us in a structured, machine-readable file;
  • withdrawal of consent: at any moment, with no effect on processing that already took place.

Email hello@korvianex.ink to use any of them. We might first check that the request really comes from you. Expect an answer inside one month; tricky or high-volume requests can stretch that by up to two more months, and we will say so if that happens.

A complaint can also go to the data-protection supervisor where you are resident, though we would like a chance to sort it out first.

10United States

For residents of US states

California and the other US states with privacy statutes give residents the right to know what personal information a business holds, to have it deleted or corrected, and to opt out of its “sale” or its “sharing” for cross-context ads.

  • Sale. None. Korvianex does not sell personal information.
  • Sharing. Measuring ads with Meta and Google may be labelled “sharing” by certain state laws. To opt out, disable tracking on the device or write to us using “Do Not Share” as the email subject.
  • Categories collected over the last 12 months: identifiers (IDFV, SDK IDs, and IDFA where tracking was allowed); commercial information (App Store purchase history); internet or other electronic network activity (in-app events); device details such as IP address; and whatever you wrote to support.
  • Equal treatment. Exercising a right never costs you a different price or a worse service.
  • Authorised agents. A person you appoint in writing can submit requests for you, and we may still confirm your identity with you directly.
  • “Shine the Light”. Californians may ask whether we disclose personal information to third parties for those parties’ direct marketing. We don’t, and we will confirm that on request.
11Children

Built for people aged 16 and up

Zen Cleaner is not designed for under-16s, and we never knowingly gather their personal data. Think a child has sent us something? Write to hello@korvianex.ink and we will erase it.
