Updated August 2026 · both entries re-read at their own catalogues, a decision table added, and the 2026 novelty framing withdrawn
This page reports what two catalogues publish about two cleaner and storage apps on one date. It does not describe how either app behaves, because nothing here rests on running them. Where a catalogue has no such field, the page says so instead of leaving a blank cell for a reader to fill in.
For the standing shortlist across the whole category rather than a two entry check, the cleaner apps roundup covers the wider field.
How to read the Ads column. Only the Play row uses it, and No there means that listing carried no Contains ads label on 16 August 2026. The label is a Google Play field and F-Droid has no counterpart to it, so the other row is not scored on it at all: a merged cell records a catalogue with no such field, not an app found to carry no advertising.
The one entry here whose catalogue answers the rating, price and ads questions
Developer darken · Rating 4.1 stars from 8,843 ratings · Install band 1,000,000+, the count Google Play prints and not a count of people · Free to install, with in-app purchases $3.99 to $7.99 per item · Data Safety: no data shared with third parties; no data collected · Play listing updated 29 June 2026, and the version it reports there is 1.7.5-rc0 · Requires Android 8.0 or newer (Google Play listing, read 16 August 2026) · Also on F-Droid: version 2.0.2-rc0, added 10 August 2026, licence GPL-3.0-only, built and signed by the original developer as the other entry is, with one Anti-Feature flag, Non-Free Assets (F-Droid entry, read 16 August 2026) · Contains ads: No · checked 16 August 2026
Google Play listing · 4.1 (8,843) · read 16 August 2026
SD Maid 2/SE is the only entry on this page whose catalogue answers the rating, price and ads questions, and the blunt part comes first: a record is not a review. Its Play listing, read on 16 August 2026, gives 4.1 stars from 8,843 ratings, an install band of 1,000,000+, a free install with in-app purchases $3.99 to $7.99 per item, no Contains ads label, and a Data Safety section declaring no data collected. Every one of those is a count or a declaration made to Google by the developer, not a finding about how the app behaves.
Read this first. Its F-Droid entry, read on 16 August 2026, is the only one on this page carrying an Anti-Feature flag. The flag is Non-Free Assets, and F-Droid's reason for this app, printed on that entry, reads: The icons, logos, mascots, marketing materials and assets are not licensed under GPL v3.
That is a statement about the licence on the artwork, and not about tracking, advertising or data. F-Droid documents a separate flag for advertising, and that one is not on this entry, which is the absence of a warning rather than a finding that the app carries none.
Its F-Droid entry, read on 16 August 2026, summarises it as a trusted assistant for your Android, to keep it clean and tidy, and the description the developer published on that entry says, word for word: This app is ad-free. Some features require a paid upgrade.
That is the project speaking about its own work, not a finding of ours. What can be set beside it is the Play listing, which carried no Contains ads label on the same date and prices its in-app purchases at $3.99 to $7.99 per item. Skip it if you want a finished version number: both catalogues carry a release candidate for it today. Choose SD Maid 2/SE over disky if you want figures you can weigh at all, because neither catalogue read for this page publishes one for the other entry.
Storage analysis, on F-Droid but not on Google Play, with no rating, price or ads label in either
Version 2.2.0, added to F-Droid on 2 June 2026 · Licence GNU General Public License v3.0 only, SPDX id GPL-3.0-only · Author Felix Nüsse · Summary published on F-Droid: A filesystem analyzer that can show you the usage of your storage! · Requires Android 11 or newer · Built and signed by the original developer, with F-Droid's guarantee that the build corresponds to the published source · Permissions listed for that build: view network connections, run foreground service and the dataSync foreground service type, show notifications, query all packages, run at startup, prevent the phone from sleeping, and three printed as raw names with no description beside them, MANAGE_EXTERNAL_STORAGE, PACKAGE_USAGE_STATS and one the app defines for itself, ten in all · Its entry carries no Anti-Feature flag; those flags record what F-Droid has flagged, so an absent one is not a finding that the app is clean · No rating, review count, install count, price or Contains ads label is published for any app in this catalogue, and there is no Data Safety section · No Google Play listing: play.google.com returned a 404 for its package on 16 August 2026 · F-Droid entry, read 16 August 2026
F-Droid entry · no rating or install count is published there to quote · read 16 August 2026
disky is the entry that neither catalogue read for this page rates, prices or labels for advertising, and that is the first thing to say about it. Google Play returned a 404 for its package on 16 August 2026, and its F-Droid entry carries no rating, no review count, no install count, no price and no Contains ads label, because that catalogue publishes none of those for any app. What the entry does give, read on 16 August 2026, is the licence, the author, the current version 2.2.0 with the date it was added, the minimum Android version, the permissions each build requests, the developer's own description, and links to the source code and the issue tracker.
Its F-Droid entry, read on 16 August 2026, summarises it as a filesystem analyzer that can show you the usage of your storage, and the description the developer published under that summary says, word for word: disky can analyze your device and show your data split by directory. Apps are also included, so you get the full picture of what uses your storage.
That is the project describing its own work, and nothing here ran it. The licence is a fact about the code and not a statement about behaviour: it is the same GPL-3.0-only the other entry carries, so on this page the licence separates the two not at all. Skip it if you want a published rating, a price or an ads label before you install anything: neither catalogue read for this page publishes any of the three for it. Choose disky over SD Maid 2/SE if you want the narrower tool and the shorter reach, because its entry lists ten permissions to the other's twenty and asks for no full network access.
The two entries are documented to very different depths, and that difference belongs to the catalogues rather than to the apps.
Google Play publishes a rating and a rating count, an install band, a price, an in-app purchase range where the app has one, a Contains ads label where the app carries advertising, and a Data Safety section. Its answers for SD Maid 2/SE are in the section above, each with the date it was read. F-Droid publishes none of those fields, for any app it carries. What its two entries do carry, read on 16 August 2026, is the app name, the developer's summary and description, the author, the licence, the three most recent versions with the date each was added, the minimum Android version, the permissions each build requests, the download with its size, signature and build log, project links, and any Anti-Feature flag. That is what this page compared, not an inventory of everything on the site.
One kind of flag does answer a question a store label would answer, though not the way a label does. Anti-Features are F-Droid's own warning flags, and it publishes the list it uses: one entry on that list is Ads, which it defines as the flag applied to an app that contains advertising. Neither entry here carries that flag. The one flag on this page is Non-Free Assets on SD Maid 2/SE, and the reason F-Droid prints for it on that app's F-Droid entry, read on 16 August 2026, is: The icons, logos, mascots, marketing materials and assets are not licensed under GPL v3.
The same list defines that flag as non-libre media in things that are not code, so it is about the licence on artwork, not about tracking or advertising, and it is easy to misread as a privacy warning. On the other entry, read the same day, there is no flag at all, which is the absence of a warning rather than a finding that the app is clean.
The licence separates the two not at all: both entries are GPL-3.0-only, and both are built and signed by their own developer with F-Droid's guarantee that the build matches the published source. A licence is a fact about the code, about what may be read, changed and passed on. It is not a privacy guarantee, not an ad-free guarantee and not a quality guarantee, and nothing above treats it as evidence about behaviour.
The dates are not one measurement either. Google Play prints when a listing was last updated. F-Droid prints the date on which one specific version was added to its repository. Neither of those is a release date, and this page prints no release date for either app, because nothing read for it carries one. SD Maid 2/SE is the plain case: it appears in both catalogues, and its two dates are six weeks apart with two different version numbers beside them. One freshness rule applies to both, stated once: a record that has not been updated for more than eighteen months is called out on this site as stale, and neither entry is anywhere near that line.
It comes down to which kind of evidence you want before installing anything, and to which job you are actually trying to do.
Take SD Maid 2/SE if you want a record you can check in full. Its Play listing answers the price, ads label, rating and data handling questions above, each dated in its section, and its F-Droid entry adds a licence, a current version, a change note and a permissions list. Accept in exchange that a Data Safety section is a declaration made to Google by the developer rather than a measurement, that the suggested build in both catalogues is a release candidate, and that its entry carries the one Anti-Feature flag on this page.
Take disky if the question is simply where the storage went and you want the narrower tool. It is a filesystem analyzer by its own summary, its permissions list is the shorter of the two, and its source is linked from its entry. Accept in exchange that neither catalogue read for this page rates it, prices it or labels it for advertising, that neither prints an install count for it, and that no other listing was read for this page to set beside them.
This page used to carry three write ups and a section it headed What we checked and found no news on. It now carries two entries, and that is worth explaining rather than papering over. An entry here needs a first party catalogue record that can be re-read on the day of writing, with the date printed beside every figure. Two of them have one. For the rest, this pass found no such record to re-read, so nothing that rested on them is left standing with a fresh date on it. Every entry that went is named in the changelog at the foot of this page, with the reason it went.
Two entries is a thin year for a category this size. Saying so is more useful than filling the gap, and neither choice above is a statement about how well either app cleans anything: nothing here rests on running them. For the standing shortlist, see the cleaner apps roundup.
SD Maid 2/SE. Its Google Play listing gives 4.1 stars from 8,843 ratings and an install band of 1,000,000+, read on 16 August 2026. disky is catalogued on F-Droid, which publishes no rating and no review count for anything it lists, and Google Play returned a 404 for its package on the same date. A missing rating there is a property of the catalogue, not a low score. Checked 16 August 2026.
It is free to install, and its Play listing prices its in-app purchases at $3.99 to $7.99 per item, read on 16 August 2026. That listing carried no Contains ads label on the same date, and its Data Safety section declares no data shared with third parties and no data collected, which is a declaration made to Google by the developer rather than an audit result. The description on its F-Droid entry states that the app is ad-free and that some features require a paid upgrade, and that is the project writing about its own work. Checked 16 August 2026.
It is one of F-Droid's own Anti-Feature warning flags, listed and defined in the Anti-Features documentation F-Droid publishes, and the reason the entry gives for this app is that the icons, logos, mascots, marketing materials and assets are not licensed under GPL v3. It is a statement about the licence on the artwork. It is not a finding about tracking, advertising or data handling, and it is easy to misread as one. That same list keeps a separate flag for advertising, and neither entry on this page carries it. Checked 16 August 2026.
Because those three columns are Google Play fields and disky has no Play listing: the store returned a 404 for its package on 16 August 2026. Its F-Droid entry carries none of the three either, because that catalogue publishes them for no app at all. The merged cell says so in words, rather than showing three cells a reader could take for a price, a clean ads record or a low score. Checked 16 August 2026.
Its own summary on F-Droid calls it a filesystem analyzer that can show you the usage of your storage, and the description under that says it shows the data on a device split by directory, apps included. Nothing read for this page states whether it deletes anything, so this page does not say either way. Its entry does list a permission for managing all files on the device, which records what the build may reach rather than what it does. Checked 16 August 2026.
No. A licence says what may be done with the code, not what a build does on a phone, and both entries here carry the same one. One of the two has a data handling declaration to read: the Play listing for SD Maid 2/SE says no data shared with third parties and no data collected, which is the developer's word to Google rather than an audit finding. F-Droid publishes no data safety section, so for the other entry there is no declaration at all, which is not the same as a clean one. What both entries do carry is a permissions list, and that records what a build may reach. Checked 16 August 2026.
Checked 16 August 2026: this page was rebuilt from what two catalogues publish, both read on 16 August 2026: the Google Play listing for SD Maid 2/SE, and the F-Droid entries for SD Maid 2/SE and disky. The version read today carried no Google Play link at all, and its only catalogue links were the two F-Droid listing links inside its screenshot captions. Not one figure was carried over from it.
The figures are new to the page. The version read today printed no rating, no rating count, no install band and no ads label for any app, and no price beyond the word free with no date beside it; where it said There are no ads for SD Maid 2/SE it named neither a source nor a date. Its Play listing, read on 16 August 2026, carries no Contains ads label, prices its in-app purchases at $3.99 to $7.99 per item and declares no data collected, and all three now appear with the date attached. The claim that it is distributed on Google Play, F-Droid and GitHub is narrowed to the two catalogues this pass actually read.
Entries removed: CleanSweep, which had a section of its own, together with the seven names in the section the page headed What we checked and found no news on: Files by Google, Cache Cleaner, WhatsApp Cleaner, Norton Cleaner, CCleaner, AVG and Avast. That section printed a date for three of the seven and none at all for the other four, and it named no catalogue record for any of them; the page put CleanSweep on GitHub releases rather than in either catalogue read here. This pass had no first party catalogue record to re-read any of it against. No block was deleted: every section whose subject left now carries copy sourced from the two catalogues.
Retracted: the heading claim that disky came back from two dormant years, and the framing that the 2.0 work on the other entry had landed but only in beta behind a 1.7 stable line. Both rested on a releases feed this pass did not re-read, and neither F-Droid entry says anything about a dormant period or a release channel. Also retracted: the sentence crediting APKMirror with matching the store and repository builds, which is a mirror rather than a first party record, and the closing paragraph built on a news argument about the built in tools in Android, which nothing read for this page supports. The 1.0.0 first stable date went with the entry that carried it.
Added: one decision table, since the page carried none at all, a dated How we verify box naming both sources, and a row for the F-Droid only entry that takes one merged cell instead of the Price, Ads and Rating columns, because those three are Play fields and F-Droid publishes none of them for any app. The Anti-Feature flag on SD Maid 2/SE, Non-Free Assets, is stated with F-Droid's own reason quoted and with what it does not mean spelled out; the version read today mentioned no flag at all. The verdict capsule was rewritten rather than added: the one read today opened on three apps that shipped something genuinely new in 2026 and named an entry this pass withdraws. The FAQ was rewritten in full: two of its five items were about entries that leave the page and a third named one of them beside the two that stay. Both screenshot strips are carried over whole, image for image, and stay in the section of the app each one shows, with the captions still naming who published each strip and linking the entry. One token was struck from both captions: each carried a GNU General Public License v3.0 only line beside the publisher, and F-Droid publishes no licence for screenshots at all, only the licence on the code. On SD Maid 2/SE the same entry this page quotes refutes it outright, because the reason it prints for the Non-Free Assets flag says the icons, logos, mascots, marketing materials and assets are not licensed under GPL v3. The claim that F-Droid keeps a separate advertising flag now links the list F-Droid publishes, rather than sitting unsourced beside dated lines. The previous version made no claim of anyone running either app, and neither does this one; what has gone from the body is its disclaimer sentence, because the dated How we verify box is the compliant place for that framing.
