Privacy Policy

The short version

Miglow stores the migraine information you record on your own device. We do not operate a server that holds your migraine records, and we cannot see, retrieve, or restore them. There is no Miglow account and no login.

We do not use analytics, advertising trackers, or tracking cookies in the app or on our website.

The most important privacy protection in Miglow is structural, not just a promise: your migraine records never reach us in the first place.

Who we are

Miglow is developed by Xinyang Li, operating as a sole trader based in Melbourne, Australia.

Contact: hello@miglow.co

We take the privacy of health information seriously and have designed Miglow to minimise the personal information we receive in the first place.

What Miglow records, and where it stays

When you use Miglow, you may record:

• Migraine episodes, including start and end times, intensity ratings, and pain locations
• Symptoms, suspected triggers, and relief methods you select
• Medications you log, including names, timing, and whether they helped
• Menstrual cycle dates, if you enable that feature
• Notes you write yourself
• App settings, such as language, appearance, and reminder preferences

This information is stored locally on your device.

Your migraine records are not transmitted to us and are not stored in any cloud service operated by Miglow. We do not operate a server that receives or stores them.

Because we do not hold your migraine records:

• We cannot read them.
• We cannot recover them if you lose your device or delete the app.
• We cannot provide them to another person or organisation because we do not have them.

How long your data is kept

We do not retain your migraine records because we never receive them.

Your records remain on your device until you delete them or remove the app. Copies may remain in a device backup if you use a backup service such as iCloud Backup.

If you contact us by email for support, we may retain that correspondence for as long as reasonably necessary to respond to your request, resolve the issue, maintain appropriate business records, or comply with applicable law.

Security

Your migraine records are stored within Miglow's local app storage and benefit from the security protections provided by your device and iOS, including device access controls and iOS data protection.

We recommend using a device passcode and keeping iOS up to date.

Because Miglow does not maintain a server-side database containing your migraine records, a breach of Miglow's systems cannot expose a server-side copy of those records.

When your records can leave your device

Information you record in Miglow may leave your device in the following situations.

Exporting or sharing a health report

Miglow can generate health reports from your records on your device.

A basic health report is available without Miglow Premium. Additional report features may be available with Miglow Premium.

You decide whether and where to share or save a report, for example by sending it to a healthcare professional, emailing it, or saving it to Files.

Miglow does not send your migraine records to a Miglow server in order to generate the report.

Once you send or save a report through another service, that service's privacy practices apply to its handling of the file.

Exporting your data

You can export a copy of your recorded Miglow data at any time.

The export is created for you to keep and manage. Once exported, the file is under your control. If you save or share it using another service, that service's privacy practices apply.

Device backups

If you use iCloud Backup or another device backup method, Miglow's local app data may be included in your device backup in the same way as data from other apps.

Those backups are managed by the relevant backup provider and are subject to its privacy practices. You can manage device backup settings through iOS.

Purchases

Miglow may offer optional paid features or subscriptions through the Apple App Store.

Payments are processed by Apple. Miglow does not receive or store your card number or other payment credentials.

Apple may provide information required to process and manage App Store purchases and subscription status. Apple handles purchase and billing information in accordance with its own privacy policy.

Subscription status is also handled by RevenueCat, described under Third-party services below.

Analytics, tracking, and advertising

Miglow does not contain:

• Advertising SDKs
• Third-party analytics SDKs
• Tracking technologies used for advertising or cross-app profiling

Miglow does include a subscription SDK provided by RevenueCat, Inc., which handles Miglow Premium subscription status. RevenueCat does not receive your migraine records.

We do not use your migraine records for advertising, profiling, or automated decisions that produce legal or similarly significant effects.

We do not sell, rent, or trade your personal information.

Our website does not use advertising trackers or analytics products operated by Miglow, and we do not place tracking cookies.

Third-party services

Miglow uses one third-party service inside the app: RevenueCat, Inc., which handles Miglow Premium subscription status.

When you start, restore, or hold a subscription, RevenueCat receives subscription and transaction information, such as an anonymous identifier it generates for that installation and the App Store purchase receipt used to confirm the subscription.

RevenueCat does not receive your migraine records. Subscription information is handled separately from them, and is not linked to a Miglow account, because there is no Miglow account.

RevenueCat handles the information it receives in accordance with its own privacy policy.

Notifications

If you enable notifications, Miglow may send reminders related to features you are using, such as an episode recording that is still open or a record you may wish to complete.

These reminders are scheduled as local notifications on your device. Your migraine records and notification content are not sent to a Miglow server in order to deliver them.

Notification permission is optional. You can change or revoke it at any time in your device settings, and Miglow continues to work without notification permission.

Our website

Our website is a static informational website hosted by Vercel Inc.

Like other web-hosting providers, Vercel's infrastructure may process standard technical information associated with a web request, such as an IP address, browser information, and request metadata, in order to deliver the website and maintain its infrastructure.

Miglow has not enabled website analytics, advertising technology, or tracking cookies.

If our website data practices change, we will update this policy accordingly.

Overseas processing

Your migraine records are not disclosed overseas by Miglow because we do not receive or hold them.

Our website uses infrastructure provided by Vercel, which operates infrastructure internationally, including in the United States. Standard technical information associated with website requests may therefore be processed outside Australia.

App Store purchases are processed through Apple's global infrastructure and are subject to Apple's privacy practices.

Subscription information is processed by RevenueCat, which operates infrastructure outside Australia, including in the United States. This is limited to the subscription and transaction information described above and does not include your migraine records.

Your rights and choices

Because your migraine records are stored locally, you can manage them directly in Miglow.

Access

You can view your records in the app.

Correction

You can edit your records in the app.

Deletion

You can delete individual records in Miglow. Deleting the app removes Miglow's local app data from your device, subject to any copies that may remain in device backups you control.

Miglow does not retain a server-side copy of your migraine records.

Portability

You can export a copy of your recorded Miglow data at any time.

You can also generate health reports from your records. A basic report is available without Miglow Premium, while some additional report features may require Miglow Premium.

Australia

If you have a privacy question or complaint, contact us at hello@miglow.co.

Where applicable, you may have rights under the Privacy Act 1988 (Cth) and other applicable privacy laws.

More information about privacy rights in Australia is available from the Office of the Australian Information Commissioner at oaic.gov.au.

U.S. consumer health privacy

Residents of Washington, Nevada, and Connecticut may have additional rights relating specifically to consumer health data.

For information about how Miglow handles consumer health data and those rights, see our separate Consumer Health Data Privacy Policy.

Other regions

Depending on where you live, applicable privacy laws may give you additional rights relating to personal information.

Because Miglow does not receive or store your migraine records, most actions relating to those records can be carried out directly in the app.

If we hold limited personal information about you for another reason, such as correspondence you have sent to our support email, you can contact us at hello@miglow.co about any rights that may apply.

Privacy requests and complaints

You can contact us at hello@miglow.co with a privacy question, request, or complaint.

We aim to respond within 30 days and will respond within any timeframe required by applicable law.

Children

Miglow is intended for people aged 18 and over.

Miglow is not directed to children, and we do not knowingly seek to collect personal information from anyone under 18.

Because migraine records remain on the user's device and are not held by Miglow, we generally cannot identify or remotely delete records stored inside an individual installation of the app.

If you believe a person under 18 has provided personal information directly to us, for example through a support email, contact hello@miglow.co.

Data breaches

Miglow does not maintain a server-side database containing your migraine records.

If we become aware of a security incident involving personal information that we do hold, such as support correspondence, we will assess and respond to the incident in accordance with applicable data breach notification laws.

Miglow is not medical advice

Miglow records information you enter and can organise and summarise patterns in that information.

Miglow does not diagnose medical conditions, predict medical outcomes, or provide medical advice. It is not a substitute for advice, diagnosis, or treatment from a qualified healthcare professional.

If you have concerns about your symptoms, diagnosis, or treatment, speak with an appropriately qualified healthcare professional.

Changes to this policy

We may update this Privacy Policy if Miglow changes or if legal or regulatory requirements change.

If we introduce a feature that materially changes how your migraine records are handled, such as an account, cloud sync, or transmission of health information to an external service, we will update this policy and explain the change before that feature is enabled for you.

We will not silently begin collecting migraine records that we previously stated remain on your device.

Where consent is required by applicable law for a new data practice, we will obtain that consent before the relevant processing begins.
