Your study data stays on your iPhone.

Who we are

Capstone is an iPhone app for electrical apprentices revising for the Capstone assessment. It requires iOS 26.0 or later. It is developed by Josh Waller, trading as Kovus, in Perth, Western Australia. Contact josh@kovus.dev for privacy questions or requests.

Unofficial study app. Not affiliated with or endorsed by any government, regulator, TAFE or registered training organisation.

Information stored on your iPhone

Capstone stores what it needs to run in a local database on your iPhone. There is no Kovus account, no Kovus server and no cloud sync, and Capstone does not upload your study database. Technical update requests are described under App updates. The local data includes:

• your first name, if you give one, your apprenticeship stage and the topics you find hardest, from set-up;
• your answers and attempt history, sessions, mistakes and progress;
• your saved workings and personal notes;
• your study plan, your Capstone date, your state or territory if you chose one, your weekly target and minutes, and how far you got through set-up;
• your reminder times;
• your recent searches in Chapters;
• your settings: appearance, answer keyboard, hints, celebrations and haptics;
• the result of the last purchase check (whether you have Full access, which purchase gave it and when it ends, if it does), so a Lifetime purchase still opens the app when the App Store can’t be reached; and
• a short log of recent problems in the app, described under Error log.

Your first name is shown only in the app, such as on your study plan, and is included if you export your progress. Device backups of your iPhone can contain this data. Apple and your backup settings control those backups.

Error log

Capstone keeps a log of recent problems on your iPhone, such as a screen that failed to load or a reminder that couldn’t be scheduled, so that support can see what went wrong if you ask for help. It keeps up to 50 entries. Each entry holds the time, where in the app the problem happened and a short technical message, with email addresses, long numbers, identifiers and your first name removed before it is saved. The log stays on your iPhone. It leaves your iPhone only if you open Email support or Report a problem and then send the email yourself.

Reminders

Reminders are local notifications scheduled on your iPhone. Notification permission is optional, and the rest of the app works without it. Reminders run only while you have Full access: if Full access ends, Capstone cancels them and keeps your choices, and schedules them again when access returns. Tapping a reminder opens Today. Nothing about your reminders is sent to a server, and Capstone does not use a push notification service.

Export and erase

Export progress, in Settings or on the Full access screen, creates a file on your iPhone and opens the iOS share sheet. The file is a copy for your records. It includes your first name, apprenticeship stage and chosen topics, your Capstone date, your state or territory if you chose one, your study plan, reminders, sessions, answers, progress, saved workings and personal notes. The app can’t load it back in. You choose where the file goes, and Kovus does not receive a copy unless you send one.

Erase all study data, in Settings or on the Full access screen, removes your study data, name, plan, reminders, saved workings, personal notes and settings from the app on this iPhone, and cancels its scheduled reminders. It keeps the result of the last purchase check, because Full access belongs to your Apple Account, and the error log, which isn’t study data. Deleting the app removes all of its local data. Copies you have exported or backed up are not erased.

Purchases

Capstone offers Full access through a free seven-day Lifetime trial, paid Lifetime as a one-time purchase, or a Weekly subscription. Apple processes these transactions through your Apple Account. The original free trial transaction date determines its end date; restoring or reinstalling does not restart it. Kovus does not receive your payment card details or your Apple Account details.

RevenueCat (RevenueCat, Inc., United States) checks whether you have Full access. Capstone does not supply RevenueCat with your name, email address or a custom account identifier. RevenueCat creates an anonymous app user identifier for your installation. It receives App Store purchase records, such as which product you bought and when, and, for a subscription, when it renews, ends or is cancelled. It also receives basic app and device metadata, such as app version, operating system, device type, locale and currency. It uses these records to provide access, validate purchases and provide purchase reporting. It does not receive your answers, study plan, saved workings or personal notes. Restoring a purchase restores Full access, not study data.

Read RevenueCat’s privacy policy and Apple’s privacy policy.

App updates

Capstone uses Expo’s update service, EAS Update (650 Industries, Inc., United States), to deliver fixes to the app’s code and questions between App Store versions. Each time the app opens, it asks the service whether an update is ready, and downloads it if there is one. The request includes a random identifier that the update software creates for this installation, the app’s runtime version and update channel, the identifiers of the updates already on your iPhone and, if an error stopped the app opening last time, a short technical description of that error. Capstone does not deliberately attach your name, answers, study plan, saved workings or personal notes to an update request. However, technical error text can include information from the error’s context. This automatic report is separate from Capstone’s redacted local error log and is not filtered by that log’s redaction rules. Expo also uses update requests to provide aggregate app-usage insights. Read Expo’s privacy policy.

Analytics, advertising and tracking

Capstone contains no analytics, advertising or crash-reporting SDK of its own, and does not track people across apps. RevenueCat’s use of purchase records is described under Purchases, and the update check under App updates.

Support emails and question reports

Email support, in Settings and on the app’s error screens, and Report a problem open a draft in your Mail app. The draft is prefilled with the app version, your iOS version, your iPhone model, the update the app is running and the error log. A question report names the question and carries only the most recent few log entries. You can read and change the draft before sending it, and Kovus receives only what you choose to send.

Links to other websites

Some links in Capstone open web pages, such as these pages, the support page and the licence for the training package wording the app uses. Those sites have their own privacy policies.

What we do not access

Capstone does not request access to your location, camera, microphone, contacts, photos or health data.

Where service data is processed

Purchase records are processed by Apple and by RevenueCat, and update checks by Expo, including in the United States. Overseas providers can be subject to the laws of the countries in which they operate.

RevenueCat and Expo handle this data for us as service providers. RevenueCat says it processes app users’ data only as our processor, under a data processing addendum that forms part of its terms of use and requires it to keep the data secure. Expo’s privacy policy commits it to reasonable security measures and says it does not sell information to third parties. Both services also see your iPhone’s IP address, as any internet service does when your iPhone connects to it.

Retention and deletion

Study data stays on your iPhone until you erase it in Settings or delete the app. Device backups and exported files can still contain it. Purchase records, including the original free trial transaction, are held by Apple and RevenueCat, and update-check records by Expo, under their own policies, linked above. Deleting Capstone does not remove a Lifetime purchase or cancel Weekly. Restore purchase brings back valid access without restarting a trial.

Access, correction and privacy complaints

Email josh@kovus.dev to ask what personal information Kovus holds about you, request correction or deletion, or make a privacy complaint. Because study data stays on your iPhone, Kovus does not hold a copy of it unless you send one. Requests about records held by Apple, RevenueCat or Expo may also need to follow that provider’s privacy process. You can find information about privacy complaints at the Office of the Australian Information Commissioner.

Changes and contact

We may update this policy when the app or its service providers change. The current version and its update date will stay on this page. Email josh@kovus.dev with a question or request.
