Effective Date: 21 October 2026
Inzention ("we", "us", "our") operates mobile applications including The System: RPG Habit Tracker, Ronin, Valhalla, Xianxia, Crawler, Stuck: ADHD Energy Toolkit, Thea, Bloom: Behavioural Activation, Twofold: Pass & Play, and Fifths: Daily Word Puzzle, along with our other iOS applications and the websites www.inzention.com, www.fifths.lol and www.twofold.games. This Privacy Policy explains what data we collect, how we use it, and your rights.
The short version: what you write inside our apps stays on your device, apart from the name and targets of a habit you create yourself. That text is sent to us so we can build the habits people ask for. We also collect usage analytics, tied to a random identifier created when you install the app. Our apps have no accounts and no logins, so we never learn who you are. On our websites, we ask for your email address only in a waitlist form, and we use it only to tell you when that app is out. We never sell your data. We never use health data for advertising or marketing.
Thea includes an optional feature that adapts your daily rituals to your menstrual cycle phase. You can use Thea fully without it.
Thea is not a medical device. It does not diagnose, treat, or predict any medical condition, and it is not a contraceptive or fertility tool. Cycle phase is a rough calculation from a date you or Apple Health supplied.
You can withdraw Apple Health access at any time in iOS Settings under Privacy & Security → Health → Thea. Deleting the app erases every cycle date it holds, whether it came from Apple Health or you entered it yourself.
Our apps can send reminder notifications if you allow them. These are scheduled on your device. We do not operate a push server and we do not collect a push token. Turn them off in iOS Settings or in the app's settings at any time.
Bloom holds more sensitive content than our other apps and sends less of it. Bloom keeps your ratings, your answers to "How do you feel now?" and the names of activities you write yourself on your iPhone, and never sends them to us or to anyone else unless you choose to share them, as described below. That includes the ratings in the behavioural activation program. Before an activity you rate the achievement, closeness and enjoyment you expect, from 0 to 10. Afterwards you rate how much of each you got, how depressed you feel from 1 to 100, and how important the activity is to you, from 0 to 10. Nothing in Bloom is used for health research.
Bloom sends us usage analytics through PostHog, like our other apps. They show which features get used, including reminders, the calendar, widgets, the paywall, purchases, the PDF summary and the review point, and whether the behavioural activation program is on. They include your answer to "What brings you here?", if you give one, such as "I'm trying to lift a low mood" or "A psychologist, GP or counsellor suggested it". When you finish an activity on your iPhone, give the program's before or after ratings for it, or answer or skip its feeling question, the event includes the activity's name, area, effort, place and length. When you finish an activity or answer its feeling question on an Apple Watch, the event records only that it came from the watch and, for a finished activity, whether you planned it or picked it. The ratings events record that you gave ratings and whether you rated importance, never the ratings themselves. When you hide, unhide, favourite or unfavourite an activity, the event includes its name and area. For an activity you wrote yourself, the word "own" is sent in place of its name. These events carry no name, email or account, because Bloom has none. They are attached to a random identifier created when you install the app, which lasts until you delete it. PostHog is set not to keep the IP address Bloom's events arrive from, and Bloom switches off the approximate location PostHog would otherwise derive from it.
Bloom has no account and no sign-in. A summary of your activities and ratings, with your answers to "How do you feel now?", leaves your phone only when you make a PDF and send it yourself, to whoever you choose. We never see it. If you add an activity to your calendar, its name and description go into the calendar you choose, and that calendar syncs wherever you have set it to. If you use Bloom on an Apple Watch, your iPhone passes your activities for today and the next seven days to the paired watch, including ones you write yourself, and answers you give on the watch go back to your iPhone. Deleting the app erases everything it holds.
Twofold sends us usage analytics through PostHog. They record when the app is installed, updated, opened or sent to the background; which games are started and finished, with how many players, how many moves and whether you had unlocked the game; for a game against the computer, the difficulty and whether you won; whether the first-run intro ended with a tap on Unlock; and when How to play or the paywall is opened. A completed purchase is sent with the product, price and currency. A purchase that does not complete is sent with the reason: cancelled, pending, failed or not verified. A restore is sent with how many purchases it restored. It also sends crash reports, which describe where the app failed and on what device and iOS version. A crash report can also include the error message recorded when the app fails. PostHog derives an approximate location from the IP address the events arrive on, as described under "Data collected automatically". It does not send player names or anything typed into the app. These events carry no name, email or account, because Twofold has none. They are attached to a random identifier created when you install the app, which lasts until you delete it.
Twofold sends nothing from TestFlight builds or during App Review. Player names, scores and game history stay on your device, and deleting the app erases them.
Fifths sends us usage analytics through PostHog: which puzzles are started, checked and solved, at which level, with the number of guesses and hints and the time taken; when How to play, the archive or the paywall is opened; when you change the theme or a reminder; whether you shared a result, as an image or as text; and whether the archive purchase or a restore completed. It also sends crash reports, which describe where the app failed and on what device and iOS version. A crash report can also include the error message recorded when the app fails. PostHog derives an approximate location from the IP address the events arrive on, as described under "Data collected automatically". These events carry no name, email or account, because Fifths has none. They are attached to a random identifier created when you install the app, which lasts until you delete it. PostHog stores them in the United States.
Fifths sends nothing from TestFlight builds or during App Review. Your puzzles, guesses, stats and streaks stay on your device, and deleting the app erases them. If you tap Send feedback, your email app opens a message to hello@inzention.com with the app and iOS version filled in. We receive it only if you send it.
Waitlists. Some of our app websites, including www.fifths.lol and www.twofold.games, have offered a form to join a waitlist before the app came out. The form closes when the app goes on sale. If you use one, we save the email address you type and the name of the website, and nothing else. We keep them in a table in Airtable, a database service. We use the address only to send the email the form described: one message telling you the app is on the App Store. It comes from hello@inzention.com through Google Workspace, which hosts our email. We never add the address to any other list, and we never sell it or share it for marketing. The email tells you how to unsubscribe. We delete the address from the waitlist within 30 days after we finish sending that email, or within 90 days of the app going on sale if we never send it, or sooner if you ask. Our copy of the email we sent you is kept with our other email, as described under "Data Retention".
Playing Fifths on www.fifths.lol. The website has a web version of Fifths, and the classic version at www.fifths.lol/classic. Your puzzles, stats and streaks are saved in your browser on that device, and clearing the site's data erases them. Both versions send usage analytics to PostHog: the pages you view and the site that linked you there, and gameplay events like the app's (puzzles started, checked and solved, with the level, guesses, hints and time taken; clues shown; results shared; theme changes). PostHog stores a random identifier in your browser's local storage, and records your browser and device type and an approximate location it derives from your IP address. The classic version also sends these events, with its own random identifier, to our web host's logs. These events carry no name or email address.
Hosting and fonts. Our websites are hosted by Vercel. Like any web host, Vercel receives your IP address and browser details with each request, and a waitlist sign-up passes through it on the way to Airtable. www.twofold.games and the classic version of Fifths load their fonts from Google Fonts, so your browser also sends Google your IP address and browser details when those pages load. www.twofold.games has no analytics.
Your app content is stored locally on your device. This includes quests, progress and streaks, rituals and intentions, journal and reflection entries, check-ins, your chosen focus areas, and any cycle dates described above. We cannot read any of it. The exceptions are the ones named above: the analytics events, and the text of a habit you write yourself. In Bloom the second exception does not apply: the name of an activity you wrote is never sent.
Data read from Apple Health, and the cycle dates you enter in Thea, are never used or disclosed for any of the following:
Bloom's analytics, described under Bloom, show that someone uses a mood app, and can include an answer that mentions low mood or a clinician. They go to PostHog, and they are never sold, rented or traded. Apart from them, we do not store health data in iCloud or any other cloud service, and we do not use any health data for health research. If you have iPhone backups enabled, your own device backup includes app data, as it does for every app on your phone. That backup is yours and we have no access to it.
We use the following third-party services:
| Service | Purpose | Data shared |
|---|---|---|
| Apple App Store | Distribution and payments | Purchase receipts |
| RevenueCat | Subscription management | A random app user ID, purchase receipts |
| PostHog | Product analytics | Usage events, crash reports from Twofold and Fifths, setup answers, subscription status, the text of habits you write yourself, a random per-install identifier, device details, and approximate location in seven apps; on www.fifths.lol, page views and gameplay events with a random browser identifier |
| Anthropic (Claude) | AI features (Stuck only) | User-submitted text for reframes and task breakdowns |
| Google Analytics | Website analytics | Pages viewed on www.inzention.com and actions on them, including taps on an app page's Android button (for example, "Want Bloom on Android? Let us know") with the app they were for; a random identifier in a Google Analytics cookie; browser and device details; approximate location derived from your IP address (website only) |
| Airtable | Waitlist sign-ups | The email address you entered and the website you used |
| Google Workspace | Our email at inzention.com | Emails you send us and our replies; the launch email to a waitlist address |
| Vercel | Website hosting | IP address and browser details with each request to our websites; waitlist sign-ups on their way to Airtable; gameplay events and a random identifier from the classic version of Fifths, in our host's logs |
| Google Fonts | Fonts on www.twofold.games and the classic version of Fifths | IP address and browser details when those pages load |
Bloom's analytics, described under Bloom, show that someone uses a mood app, and can include an answer that mentions low mood or a clinician. Apart from that, no health data is shared with any service in this table. Your cycle data moves between Thea and Apple Health on your own device, and nowhere else. If you have Apple Health iCloud sync turned on, Apple syncs it under your own settings and your own agreement with Apple.
We do not sell, rent, or trade your personal data. We share data only with the third-party services listed above, and only to the extent necessary to operate our apps and websites. These services are overseas recipients of the data they hold for us. Airtable and PostHog hold it in the United States. Vercel, Google, Apple, RevenueCat and Anthropic are United States companies and may hold it in the United States or in other countries where they run facilities.
App data stored on your device persists until you delete the app. Analytics data is retained for up to 12 months. Waitlist email addresses are deleted as described under "Our websites". If you contact us via email, we retain that correspondence for up to 24 months. Bloom's analytics, including any answer to "What brings you here?", are kept for up to 12 months like our other analytics. Apart from them, we hold no copy of your health data, so there is nothing else on our side to retain or delete.
Our apps are not directed at children under 13. We do not knowingly collect personal data from children under 13. If you believe we have collected data from a child, contact us and we will delete it.
You have the right to:
If you think we have mishandled your personal information, email contact@inzention.com and we will reply within 30 days. If you are not satisfied with our reply, you can complain to the Office of the Australian Information Commissioner at www.oaic.gov.au.
We use industry-standard security measures to protect your data. Because most data is stored locally on your device, the attack surface is minimal. No data is transmitted without encryption.
We may update this Privacy Policy from time to time. Changes will be posted on this page with a new effective date. Continued use of our apps after changes constitutes acceptance of the updated policy.
