Privacy Policy

Last updated: October 27, 2026

This Privacy Policy describes how Apis Systems LLC ("we", "us", "our") handles information in the applications we publish. It applies to all of our applications unless an application section below states otherwise.

Summary: most of our applications do their work on your device. Your files, and what our apps find in them, never leave it. A few things can: anonymous counters of which features get used, which you can switch off, and a feedback report, but only if you write one and press Send. Disk Reviewer also asks the App Store once a day whether a newer version of itself exists, which carries nothing about you. Foliata identifies plants on the device, and sends one photograph to our server only when it cannot name what it sees and you are online; that too can be switched off. WTFAustin is a live map, so it needs our server: it keeps an anonymous account, and, only when you create them, a home pin, the reports you post and a token for notifications. There is no advertising and no tracking of any kind, and we sell nothing. DeckMirror makes no network requests at all.

1. Data we collect

What our applications process to do their job, such as the files they scan, their names, paths, sizes and what a scan found, stays on your device and is never sent to us. That is the part that matters most, and it has not changed.

The exceptions are listed here and described in full below:

We do not collect contacts, browsing data, or any advertising identifier, and none of our applications contains an advertising SDK. Crash reports and location are collected only in the narrow cases named above, and only after you have allowed them or placed a pin yourself.

2. How we use information

Usage counters tell us which parts of an app people actually use, so we can improve those parts and stop guessing. Feedback is used to understand and fix the problem you reported, and to reply to you if you left an address. A WTFAustin home pin is used for one thing: deciding which incidents are close enough to it to notify you about. That is all. We do not profile you, build advertising audiences, or make automated decisions about you.

Information that our applications process to perform their function, such as the file listings in a disk cleanup tool, is processed locally on your device and is never transmitted to us or to anyone else. The exceptions are the Foliata photograph described above, which is transmitted for a single purpose (naming the plant in it) and is not kept afterwards, and the WTFAustin data listed in its section, which the app cannot work without.

3. Sharing with third parties

We never sell, rent or trade data, and we share nothing for advertising. These processors handle data on our behalf:

Apple and Google process purchases and subscriptions, and Apple answers Disk Reviewer's once-a-day question about whether a newer version is on the App Store; we never receive your payment details. Beyond these, nothing is shared, including with advertisers, data brokers, or tracking networks. There are no tracking SDKs in our applications.

3a. How long we keep it

Feedback reports and their attachments are kept for up to 12 months and then deleted; we may delete a report sooner once it has been dealt with. Where a report's attachments and reply address are removed as soon as it has been dealt with, the text of the report may be kept longer, as a record of what was reported and what we changed. Usage counters are aggregate and are not tied to you, so there is no individual record to retain or remove. The diagnostic log on your Mac keeps the last seven days and prunes itself; it never leaves the device unless you attach it to a report.

A photograph sent for identification is not retained at all: it exists for the length of the request and is gone when the answer comes back. What remains is a number (how many such requests an installation has made) which we keep for as long as the installation exists, because it is what makes the free allowance mean something.

What WTFAustin stores on our server stays until you remove it or delete your account. Turning notifications off deletes the push token at once.

Photographs you take in Foliata stay on your phone. Every scan is kept in the app’s own storage so that your scan history and your herbarium can show it later, and it stays there until you remove the find, delete your account, or uninstall the app; we do not age them out. They are not uploaded, not backed up to us, and not readable by other apps. Deleting your account removes them from the device along with everything else the app had stored.

5. Your rights

You remain in full control of everything our applications touch on your device. For what we do hold, you can ask for a copy, a correction, or its deletion, and we will act on it. Write to [email protected] from the address you used, or describe what you sent well enough for us to find it; we respond within 30 days. Disk Reviewer and DeckMirror never create an account. Foliata signs you in anonymously the first time it opens; Settings, then your account, then Delete account removes that account, the copy of your herbarium and the record of your launches in one step. WTFAustin also signs you in anonymously; Settings › Delete account erases what is listed in its section above.

You can also stop the usage counters at any time in the app's settings, without asking us. Because they are anonymous and aggregate, they hold nothing tied to you that could be retrieved or erased individually.

6. Children's privacy

Our applications are not directed at children and do not knowingly collect personal information from them.

7. Our websites

This website (apissystems.dev) is a static site served through Cloudflare. Like most hosting providers, Cloudflare processes basic technical request data, such as IP addresses, to deliver the site and protect it from abuse. We use Cloudflare Web Analytics, a privacy first, cookie free service that shows us aggregate page statistics and cannot identify individual visitors. The site sets no cookies and runs no advertising or cross site trackers.

Two forms on this site send what you type to us: the contact form on the home page and the waitlist on the direct booking page. The contact form is delivered to our inbox by FormSubmit (formsubmit.co). The waitlist is stored with Cloudflare, which hosts this site, and FormSubmit sends us a copy of each new signup by email. The waitlist keeps your email address, the number of homes you rent out, and, if you fill them in, your state and how guests book with you today, together with the link or site that brought you to the page and the country your request came from. We use it to send one email when it launches and to judge whether it is worth building. If we decide not to build it, the list is deleted. You can ask to be removed at any time by writing to [email protected]. See FormSubmit’s privacy policy.

Until October 27, 2026, the direct booking page also took pre-orders, paid on a checkout page run by Stripe. Stripe collects your card details and we never see them; we receive your email address, the amount and the payment status, which we use to deliver what you paid for or to refund you. See Stripe’s privacy policy.

We also run diskreviewer.com, a single page site for Disk Reviewer that we advertise. It is hosted the same way, and it uses TelemetryDeck, the same analytics provider as the app, to record page views and whether a visitor followed the link to the Mac App Store. TelemetryDeck sets no cookies and does not fingerprint your device. Instead of an identifier that follows you around, it derives a one way hash from your IP address, your browser's user agent string and a salt that changes every day, so a visitor cannot be recognised the next day or on any other site. It also records the page address, including any campaign parameters an advertising link carries, together with coarse browser, operating system and country information. We use this only to see whether our advertising reaches people who actually want the app. No cookie banner is required because no cookies are set, and that site carries no advertising or cross site trackers either.

8. Changes to this policy

We may update this policy from time to time, for example when we release a new application. The date at the top of this page always reflects the latest revision. Material changes will be described in the relevant application section.
