This Privacy Policy explains how Dazlight (“we”, “us”) handles information in connection with the Shiftwise: Shift Sleep Planner mobile application (the “App”).
Shiftwise keeps your roster, sleep journal and planning settings on your device without a Shiftwise account. Premium subscriptions use store platforms and RevenueCat. Some versions also offer voluntary usage sharing, which is off by default and described below. We do not show ads or use advertising trackers in the App.
By using the App, you agree to this Privacy Policy. If you do not agree, please do not use the App.
The App is provided by Dazlight. For privacy questions, contact us at info@dazlight.com.
Country of operation: Ukraine.
Other Dazlight apps and the website have their own privacy policies. This document applies only to Shiftwise. For the website (forms and analytics), see the Website Privacy Policy.
When you use Shiftwise, you may enter information such as:
This information is stored locally on your Device. We do not operate an account system that uploads this content to Dazlight servers as part of normal App use.
You can export local data from the App as JSON copied to your device clipboard. Anything you then paste or save elsewhere is under the control of that destination. If you uninstall the App, clear App data, or reset your device without keeping a copy, local information may be permanently deleted.
In normal use, Shiftwise does not collect:
If you enable reminders or notifications, your Device’s operating system may deliver them locally based on settings you choose in the App. We do not need a Dazlight account for that.
Your device's operating system or app store platform may provide crash or diagnostic reports. We use reports available to us to fix bugs and improve stability, not for advertising.
If you email us or use a support form on our website, we will receive the information you send (for example your email address and message) so we can respond. We keep that correspondence only as needed to help you and run our support.
Google Play or the Apple App Store processes purchases. Shiftwise uses RevenueCat to check Premium access and manage subscription status. RevenueCat and the store platform process the purchase and subscription information needed for those functions, including an app installation or customer identifier. Shiftwise does not send your roster, sleep records or planning details to RevenueCat. Prices, renewal terms and any eligible trial appear before purchase. Store platforms and RevenueCat have their own privacy practices; purchase records may be subject to their retention and legal requirements.
Some Shiftwise versions offer optional usage sharing in setup or Profile. It is off by default and is not required to use the App. If you enable it and a capture service is configured, Shiftwise may send a limited set of usage steps and purchase-flow outcomes to PostHog over HTTPS. The payload can include categorical event names and properties, a random installation identifier, a random event identifier and an event time rounded to the minute. It does not include names, shift or sleep times, sleep duration or quality, notes, journal entries or precise location. The service receives ordinary connection information such as an IP address when a request is made. The App is configured to avoid geolocation enrichment and person profiles.
Pending usage events are held locally in a queue of at most 100 events. Turning sharing off cancels pending sending and clears that queue, local counts and the random identifier. Events already received by a configured service cannot be removed by switching the setting off; contact us to ask about a deletion request. If no capture service is configured, no usage events are sent remotely.
If you choose to import an .ics calendar file, Shiftwise reads the file you select to show and save shifts on your device. The imported roster is not uploaded to a Dazlight account as part of normal App use.
On-device App data is used by the App on your Device to provide sleep and shift planning features you request.
Support messages are used only to respond to you and improve support quality.
Crash and diagnostic reports, if available to us, are used for maintenance and bug fixing. Subscription information is used to validate Premium access and support purchases. Optional usage events, if you enable sharing and a service is configured, are used to understand how people reach core features and where the App needs improvement.
We do not use your roster or sleep journal for advertising, and we do not sell Personal Data.
We do not share your on-device Shiftwise roster or sleep journal with advertisers or data brokers. RevenueCat and store platforms process subscription information. If you opt in to usage sharing in a version with a configured capture service, PostHog processes the limited event data described above. These services do not receive roster or sleep journal content from Shiftwise. A JSON export is copied to your clipboard only at your request; its later destination depends on what you choose to do with it.
We may disclose information only if:
App distribution platforms (such as Google Play) have their own privacy practices for store accounts, downloads, and reviews. Those are controlled by the platform, not by Shiftwise’s in-app data storage.
Local roster, sleep and settings information remains on your device until you delete it, clear App data, or uninstall the App. Pending usage sharing is limited to 100 local events and is cleared when you turn sharing off. Events already delivered to a configured service follow that service's retention settings; contact us to request information about deletion. Store platforms and RevenueCat retain subscription records under their own requirements.
Support emails or form submissions we receive are kept only as long as needed to handle your request and meet basic operational or legal needs, then deleted or minimized when no longer required.
Shiftwise does not automatically upload your local roster or sleep journal. Subscription services and, where configured and enabled, voluntary usage sharing may process their limited data on infrastructure outside your country.
If you contact us, your message may be processed where we operate (including Ukraine) or where our email/support tools are hosted. We take reasonable steps to handle that information securely.
You can:
Depending on where you live (for example under GDPR or similar laws), you may have rights to access, correct, delete, or restrict certain Personal Data we hold about you (typically support correspondence), and to object to certain processing. To exercise these rights, email info@dazlight.com.
We may need to verify your request and may decline requests where the law allows (for example if we do not hold the data, or retention is legally required).
We design Shiftwise so sensitive roster and sleep records stay on your device. A clipboard export can be read by apps you choose to paste it into, so handle it carefully. No method of electronic storage is perfectly secure. Protect your device with a passcode or biometrics and keep your system updated.
The App is not directed to children under 16. We do not knowingly collect Personal Data from children under 16. If you believe a child has provided Personal Data to us through support channels, contact us and we will take appropriate steps.
The App or our website may link to third-party sites or stores (for example Google Play). Their privacy practices are their own. We recommend reading their policies.
We may update this Privacy Policy from time to time. We will post the updated version on this page and change the “Last updated” date. Where required, we may provide additional notice.
Continued use of the App after changes take effect means you accept the updated Policy.
