DIO Legal

Privacy Policy

Version 1.0 · Effective 5 August 2026

DIO ("DIO," "the app") is made by Elitec LLC ("Elitec," "we," "us"). This policy explains in plain language what data DIO handles, where it lives, and what we can and cannot see. It is one document for everywhere DIO is sold, which is every App Store territory.

The short version: DIO has no accounts, no backend, and no access to what you write. Your data lives on your device and in your own iCloud. Your content is never sent to Elitec LLC. The one thing DIO can send, and only with your permission, is anonymous usage statistics: which screens open and which tools get used, never a word you wrote and never anything that identifies you.

1. What DIO stores, and where

Everything you create in DIO is stored on your device: your thoughts, bins and their contents, to-dos, habits, DIO calendar events, Dopamine Dive activities, your themes and layout choices, and your notification preferences.

If you are signed into iCloud, DIO also writes a copy to your iCloud Key-Value Store. That is Apple storage inside your own iCloud account, provisioned to your Apple ID. It is what lets a new iPhone signed into the same Apple ID repopulate with no login. Elitec LLC has no console, credential, or interface through which to read it. We hold no copy of any of it.

There is no Elitec LLC server, no user database, and no account record anywhere. We do not sell, rent, share, or trade your information, because we do not have it.

DIO also keeps a small on-device diagnostics archive supplied by Apple's MetricKit: crash and performance summaries about the app itself. It contains none of your content and is never transmitted. It is cleared by Delete All My Data.

2. What leaves your device

Very little, and none of it is what you write.

Anonymous usage statistics, only with your consent. DIO can send anonymous usage signals through TelemetryDeck, a privacy-focused analytics service, and it asks you first: the choice appears once at the end of the welcome screens and lives permanently in Settings under Usage data. It starts off everywhere, and stays off until you turn it on. A signal says things like which screen opened or which tool ran, with general device facts the service attaches to everything: device model, iOS version, app version, language, region, time zone, and display and accessibility settings such as text size, along with a random session identifier and coarse usage counters the service keeps (when you first used DIO, how many sessions there have been, how many days you have used it, and how long a session runs on average). Signals are tied to an identifier iOS gives to apps from the same developer, hashed on your phone before anything is sent and hashed again by the service. It is not a name, an email, or an account, because DIO has none of those, and we have no way to turn it back into one. Nothing you write ever rides along: not a thought, a to-do, a habit name, an event title, or a single character you typed. DIO's App Store privacy card declares exactly this: a device identifier and product interaction, not linked to identity, never used for tracking.

Turning the switch off records nothing further and changes nothing else about the app. Signals already sent are not linked to your identity, and we have no way to connect them to a name, an email, or an account, because DIO has none of those. Usage signals are kept by our analytics provider for up to 12 months and then deleted.

Your iCloud copy goes to Apple, not to us. It is your own iCloud account, on your own Apple ID, described in section 1. Elitec LLC has no way to reach into it.

Subscription checks with Apple. DIO asks Apple's StoreKit whether your Apple ID has an active subscription. That exchange is between your device and Apple. We never see your Apple ID.

Email you choose to send us. If you use Report a Bug or Suggest a Feature in Settings, DIO opens your own email app with a draft. Nothing is sent until you send it. Because it comes from your email app, your email address travels with it; that is how we reply, and we have no other way to reach you.

A bug report also carries a short technical block, and this is the whole of it: the app version and build, your iOS version, your iPhone's hardware model identifier (for example "iPhone17,2", which is the model, not the name you gave your phone), your language, your region, and whether you have an active subscription. Six lines, and nothing else. It contains nothing you have written in DIO. We use your address and that block only to answer you and to work out what went wrong. We keep them for up to 12 months after the conversation ends, and sooner if you ask; see section 6.

Every other feature works with no network at all. DIO in airplane mode is DIO.

3. Permissions DIO may request

All three are optional, all three are asked for in context, and DIO works without any of them.

Notifications. For reminders you set on to-dos, habits, time-blocks, and events, for the end of a focus timer, for an optional daily summary and occasional gentle nudges that are listed in Settings and can be turned off there, and for a heads-up before a free trial converts. Every notification is scheduled locally on your device by iOS. DIO has no push capability and no server to push from, so nothing can reach you that your own device did not schedule.

Calendar. So your real events show beside your own and the day reads as one picture. DIO never creates, edits, or deletes anything in your Apple Calendar. iOS has no read-only permission level for events, so the prompt asks for full access, which is the only way to read a calendar at all. DIO uses only the reading half of it, and there is no code in the app that writes. When you mark an imported event done, hide it, or change its category in DIO, that choice cannot be written back to your calendar, so DIO records it on your own device instead, and it is cleared by Delete All My Data.

Microphone, contacts, photos, location, health data. None of these are requested, because DIO does not use them.

4. Taking your data with you

Settings, Privacy and Data, Export a copy of my data.

DIO writes a single readable text file holding your pile, every bin item with its state, your to-dos, habits, DIO calendar events, and Dopamine Dive list, then hands it to the standard iOS share sheet so you can save it, mail it to yourself, or move it anywhere you like. It is built on your phone, nothing is uploaded to make it, and we never see it.

Events imported from Apple Calendar are deliberately left out: those belong to your calendar account rather than to DIO, and DIO only ever reads them.

This is DIO's data portability mechanism. Because Elitec LLC holds no copy of your data, we could not fulfill a portability request by sending you a file; the app does it directly, offline, in a format you can open.

5. Deleting your data

Delete All My Data (Settings, Privacy and Data, Leaving DIO) erases all DIO data on that device, removes DIO's data from your iCloud Key-Value Store, deletes the on-device diagnostics archive, cancels every scheduled notification, and leaves behind a single timestamp, which is what signals your other devices to clear their copies. There is no undo.

Deleting the app alone removes what was on that phone but leaves your iCloud copy in place, so reinstalling brings your things back. This is deliberate. If you want it gone, use Delete All My Data first.

Your subscription is separate from your data. Deleting your data does not cancel it, and neither does deleting the app. The subscription is with Apple and is canceled in your Apple account.

The only thing held anywhere else is the anonymous usage history described in section 2, and only if you switched it on. Delete All My Data stops any further signals immediately. To have signals already recorded removed as well, write to dio@elitechq.com and we will delete them from our analytics provider.

6. Your rights, wherever you live

One thing shapes all of this: nothing you write in DIO reaches Elitec LLC. The only things we ever hold are your email address, if you write to us, and the anonymous usage signals in section 2, if you switched them on. Those signals are not linked to your identity and carry nothing you wrote, so most requests below are answered by the app itself, and the rest by one email to us.

Write to dio@elitechq.com for anything in this section. A person reads it. We will not ask you to create an account to make a request, because there are no accounts.

If you are in the EU, the EEA, or the UK (GDPR and UK GDPR). Nothing you write in DIO is processed by Elitec LLC. What you write stays on your device, and if you use iCloud it is also held in your own iCloud account. That sync is between you and Apple, under your Apple ID and Apple's own terms, and Elitec LLC is not a party to it. The one processing Elitec LLC carries out is the anonymous usage analytics described in section 2, and only where you have switched it on. For that processing Elitec LLC is the controller, the lawful basis is your consent under Article 6(1)(a), and TelemetryDeck acts as our processor. You can withdraw that consent at any time, with no effect on the app, in Settings under Usage data. Withdrawal does not affect the lawfulness of anything processed before you withdrew.

Your rights of access, rectification, erasure, restriction, objection, and portability apply in full. In practice the app serves most of them directly, because almost nothing is held anywhere else. Access and portability are met by the export in section 4, which writes everything you created in DIO to a readable file on your own phone. Erasure is met by Delete All My Data, which clears this device and your iCloud copy, and by deleting the app; for usage signals already sent, write to dio@elitechq.com and we will delete them from our analytics provider. If you have written to us, we hold your email address and what you told us for up to 12 months after the conversation ends, and sooner if you ask.

Nothing you write in DIO is ever transferred anywhere. Where you have switched usage signals on, those signals are handled by TelemetryDeck on servers in the European Union, and Elitec LLC, a Colorado company, views the resulting aggregate counts from the United States. That access is covered by the European Commission's Standard Contractual Clauses. There is no automated decision-making that produces legal or similarly significant effects. You may complain to your national data protection authority, and we would rather you told us first.

EU Digital Services Act. Elitec LLC's trader contact information is displayed on DIO's App Store product page for consumers in the European Union, as Articles 30 and 31 require of Apple as the platform. The trader contact address shown there is support@elitechq.com, which is an Elitec LLC account-level address used for that purpose. For anything about privacy, your data, or this policy, use dio@elitechq.com.

If you are in California (CCPA and CPRA) or another US state with a privacy law. Elitec LLC collects two categories. First, if you write to us: your email address and the contents of your message, an identifier and customer-records information, collected to answer you and kept for up to 12 months after the conversation ends. Second, if you switched usage signals on: identifiers, product interaction, and internet or other electronic network activity information, collected for analytics and kept for up to 12 months. Nothing you write in DIO is collected at all. We do not sell your personal information and we do not share it for cross-context behavioral advertising, under any definition, for any price, ever. No category is sold or disclosed for a business purpose. We process no sensitive personal information. Exercising any right, including the right to know, delete, correct, or opt out, is a single email to dio@elitechq.com, and we will not discriminate against you for asking.

If you are in Australia (Privacy Act 1988 and the Australian Privacy Principles) or New Zealand (Privacy Act 2020). The privacy contact for Elitec LLC is reachable at dio@elitechq.com. Nothing you write in DIO is disclosed to anyone, in Australia or overseas. The one overseas recipient of anything is TelemetryDeck, in the European Union, and only of the anonymous usage signals in section 2, and only if you switched them on. Your iCloud copy stays inside your own Apple account and is handled by Apple under Apple's own privacy policy.

If you are in Canada (PIPEDA) or Quebec (Law 25). The same contact applies for access, correction, and withdrawal of consent. The only consent DIO asks for is the usage signals in section 2, and the switch in Settings under Usage data withdraws it at any time. If you have written to us, we hold your email address and what you told us, for up to 12 months after the conversation ends. Apart from that, the only thing Elitec LLC holds is the usage signals in section 2, which are not linked to your identity and contain nothing you wrote. There is no account record and no profile of you.

Everywhere else. The same protections apply. We did not write a stricter version for one region and a weaker one for another.

7. Children

DIO is not directed at children under 13 and we do not knowingly collect information from them. DIO carries a low App Store age rating because it contains nothing objectionable, not because it is designed for young children. If you believe a child has provided information to us, write to dio@elitechq.com and we will remove it.

8. Security

Your data is protected by your device. It is stored inside DIO's app container, encrypted at rest by iOS under a key protected by your passcode, and cannot be read until you enter your passcode for the first time after the phone is powered on. Your iCloud copy is protected by your Apple ID and its two-factor authentication.

There is no password to steal, no session token to hijack, and no server to breach. The categories of incident that dominate reports for apps like this one are not mitigated here; they are absent.

What DIO cannot protect against is someone picking up your phone while it is already open in front of them. A passcode, Face ID, and a short auto-lock are the real defence, and they are iOS settings rather than DIO ones. We say so plainly in the app rather than implying otherwise.

DIO collects no biometric data and reads no HealthKit data. If you told DIO during setup which areas you struggle with, that answer is stored on your device like everything else you write, never leaves it, and never rides along with a usage signal. It is cleared by Delete All My Data.

9. Apple's role

Apple is the merchant of record for your subscription. Apple takes the payment, issues the receipt, handles billing and refunds, and manages cancellation. Elitec LLC never receives or stores your payment details, card number, or billing address. Apple's own privacy policy governs what Apple does with that information.

Manage or cancel a subscription in your Apple account, or from the bottom of DIO's Settings, which opens Apple's own sheet.

10. Changes to this policy

If we change this policy we will update this page and the effective date, and material changes are highlighted in the app before they take effect. The full text is bundled inside the app, so what you agreed to never depends on a website staying up. Continued use of DIO after a change means you accept the updated policy.
