Fernnote Privacy Policy
Effective 7 November 2026
On this page
The short version
Fernnote is a personal log for your GLP-1 medicine, weight, protein and how you feel. You do not need an account, and we do not ask for your name, e-mail address or phone number. Your entries stay on your phone, and we do not receive them. Crash reports help us fix the app. Apple or Google handle your purchases. We do not sell the data we hold. Write to us at info@mobixify.com with any question about your data.
Who we are
The controller is MOBIXIFY LTD (Mobixify), company number 16138122. Contact: info@mobixify.com. Company information: mobixify.com/company/.
What stays on your phone
Your medicines, doses, dose times and injection sites, weight, food and protein, how you feel and your notes, your goals, settings and reminder times are saved on your phone and are not sent to us. The food list with protein values is built into the app and works on your phone. If you turn reminders on, your phone creates them, and you can hide the medicine's name in them. When you make a report or a backup file, the app builds it on your phone, and it goes where you choose to share or save it, for example to your doctor. A device backup made by Apple or Google may include this data; it goes to your own Apple or Google account, not to us.
What we collect, why, and on what basis
| What | Why | Basis |
|---|---|---|
| Crash reports: the technical record of a crash, device model, operating system, app version and random installation IDs. Your entries are not part of crash reports. | To find and fix bugs | Legitimate interests; your consent where the law requires it |
| Purchases: a random app user ID, your purchase history and subscription status in this app, app version, device type, operating system and IP address. We do not see your card details. | To unlock Pro, restore purchases, prevent fraud and keep tax and accounting records | Contract (our Terms); legitimate interests; legal obligation |
| Updates and technical data: IP address, operating system, app version and standard request details | To keep the app up to date, working and secure | Legitimate interests |
| What you write to us: your e-mail address and your message. If you write from the app, the message it prepares includes the app version, your system version and your device model; you can remove them before you send it. | To answer you | Legitimate interests; contract where your message is about a purchase |
This information is collected automatically while the app is online; your messages reach us by e-mail. We do not use any of it for advertising.
Your choice. Where the law requires it, the app asks before using crash reporting; elsewhere crash reports start switched on, and the app tells you so once. You can change this at any time in Settings, and the app works the same either way.
Technical logs. Our servers keep short-lived technical logs, including your IP address and the User-Agent header of each request, which names the app or its network software and its version and, on iPhone and iPad, can show the version of the system.
Store update check. When the app starts, it checks whether a newer version is available through the App Store or Google Play and through a request to our server. Apple and Google each handle their part as separate controllers. Our request does not carry a user or device ID.
Refunds. If you ask Apple or Google for a refund, we may share information about that purchase with them so that they can decide your request. We do this with your consent, given in the Terms; you can withdraw it at any time by writing to us.
Who receives your information
- Service providers that process data for us on our instructions and must protect it as this policy describes: hosting, crash reporting, purchase processing and app update providers.
- Apple and Google, as separate controllers, for the app stores, payments and their part of the update check. Their own privacy policies apply to the data they hold.
- Authorities, advisers and others, where the law requires it, to protect safety or to defend legal claims. If we sell or reorganise the business, data may pass to the new owner under this policy.
We do not sell the data we hold or give it to advertisers or data brokers.
Transfers outside the UK
Your information may be handled outside the UK, including in the United States. We rely on the UK-US data bridge for certified recipients, the UK Addendum to the standard contractual clauses where a provider's terms use it, and otherwise the UK's standard data transfer terms. Email info@mobixify.com for a copy of the safeguards.
How long we keep information
- Data on your phone: until you delete it, use Delete all data in Settings or uninstall the app.
- Crash reports: 90 days.
- Purchase records: while the app is on sale and then 6 years, for tax and accounting.
- Technical logs: a short time.
- Messages to us: 24 months after the last message. Records of data requests: 3 years after we close the request.
Your rights
You can ask us for access to your personal data, to correct it, to delete it, to restrict its use, and to receive a copy in a portable format. Where we rely on legitimate interests, you can object at any time, and we will stop unless we have compelling grounds or need the data for legal claims. Where we rely on your consent, you can withdraw it at any time; this does not affect what happened before. Your entries are on your phone, so you can see, change, export or delete them yourself in the app.
To use a right, write to info@mobixify.com. As there is no account, adding the order number from your Apple or Google receipt helps us find a purchase record. We will act on your request within one month (up to two more for a complex request, and we will tell you why). Ask Apple and Google about the data they hold.
If you are not happy with how we have handled your personal data, tell us first at info@mobixify.com. We will acknowledge your complaint within 30 days, look into it without undue delay and tell you the outcome. You can also complain to the Information Commission (ICO), the UK's data protection regulator, at ico.org.uk/make-a-complaint.
If you live in a US state with a consumer health data law, our Consumer Health Data Privacy Policy (https://mobixify.com/store/apps/fernnote/consumer-health-data/) describes these practices in that law's terms.
Adults
Fernnote is made for adults aged 18 and over, and the app asks you to confirm this once. We do not knowingly hold personal data from children. Parents and guardians can write to info@mobixify.com with any concern.
Security
Connections are encrypted and access to data is limited. If a personal data breach puts your rights at risk, we will tell you and the Information Commission (ICO) as the law requires.
Changes to this policy
If we change how the app handles personal data in a material way, we will update this page and its effective date before the change takes effect, and say so in the release notes on the store.
