Privacy Policy

SpectraCrop Privacy Policy

Effective date: November 5, 2026

Introduction

This Privacy Policy explains what information the SpectraCrop iOS app (the “App”) collects, how it is used and shared, and the choices you have. “SpectraCrop”, “we”, “our” and “us” refer to the provider of the App and of the SpectraCrop service.

Data controller: SPECTRACROP ApS, Hovedgaden 55, Hellevad, 6230 Rødekro, Denmark, info@spectracrop.com.

The App does not track you across other companies’ apps or websites, does not show advertising, does not contain analytics or advertising software, and we do not sell your personal information.

Information We Collect

1. Account information

To use the App you create an account with:

  • Email address – identifies your account and is used to sign in.
  • Password – sent over an encrypted connection to our server to create your account and verify your sign-in. The App does not store your password on your phone.

When you sign in, our server issues a session identifier, which the App stores securely in the iOS Keychain to keep you signed in.

2. Readings

Readings you transfer from your SpectraCrop meter are stored on your phone and on our server, linked to your account. The App sends them to our server when you sync, which also happens automatically after a transfer and when you sign in. Our server calculates results for each reading, such as P-predict and a result class, and the App downloads them. A reading contains:

  • The measurement values (such as F0, FMax, Fv/FMax, Vj, M0 and PI), a quality indicator, and the raw measurement data received from the meter.
  • The date and time of the measurement and of synchronization.
  • An optional description you enter.
  • An optional location (latitude and longitude; readings entered by hand in earlier versions of the App may also have an altitude). See section 3.
  • The results calculated by our server.

3. Location

Location is optional. The App only uses your location while the App is open on the screen. It never uses it in the background.

If you allow location, the Location option on the App’s New screen is on (it is on by default), and Automatic Transfer is on, the App follows your position while your meter is connected. It uses this to save, with each reading, the precise position where that reading was measured. You can switch the Location option off at any time, or refuse location access, and the App then saves readings without a position. When you download readings with Download Readings, you choose whether to add your current position.

Positions that are not saved with a reading are kept only in the phone’s memory, are never sent to our server, and are discarded when the App is closed.

4. Device identifier

The App generates an identifier for this installation (based on Apple’s identifier for vendor), stores it in the iOS Keychain, and sends it with requests to our server so the server can recognise the installation, for example for session management. It is not used for advertising or tracking.

5. Bluetooth and your meter

The App uses Bluetooth to find and connect to your SpectraCrop meter and download the readings stored on it. While doing so it uses the meter’s name, its Bluetooth identifier and signal strength on your phone only. These are not sent to our server, except the meter’s name in a support email you choose to send (section 6).

6. Support diagnostics

The App keeps a short diagnostic log on your phone: the last 500 events, such as Bluetooth connection steps, commands sent to the meter, server status codes and error codes. It does not contain passwords, session identifiers, your location or the content of your readings.

The log stays on your phone. It is only sent to us if you choose Contact Support and send the resulting email. That email also includes the App version, iOS version, phone model, the name of your meter, your account email and any error code. You can review and edit the email before sending it, and it is sent with your own email app.

We do not use your information for advertising, profiling or automated decision-making.

How We Share Your Information

  • Hosting provider: our server and its database are operated by a hosting provider that processes data on our behalf and under our instructions.
  • Apple: the map in the App is provided by Apple (MapKit). To show the map, your phone requests map data from Apple, as with any app that shows an Apple map. Apple handles this under its own privacy policy. The App does not send your readings to Apple.
  • Legal requirements: we may disclose information if required by law or by a valid request from a public authority.
  • Business transfers: if SpectraCrop is merged, acquired or sells its assets, information may be transferred as part of that transaction, subject to this policy.

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

Data Retention

  • Account and readings on our server: kept while your account exists. When you delete your account, your personal information is deleted within 90 days. Only anonymised measurement values are kept (see “Deleting Your Account”).
  • Data on your phone: readings are stored in the App on your phone. Signing out or deleting your account removes them from the phone. Readings that haven’t been synced are lost when you sign out. Deleting the App removes all of its data from the phone, except the device identifier and session information in the iOS Keychain, which may remain until the phone is reset. Which readings you have moved to the archive is stored only on your phone, not on our server, so it is lost in these cases and when you sign in on another phone; the readings themselves are kept.
  • Support emails: kept as long as needed to handle your request and any follow-up, and then deleted.

Deleting Your Account

You can delete your account at any time in the App: User → Delete Account. You can also email us at info@spectracrop.com.

You are signed out straight away and can no longer sign in. Within 90 days we permanently delete your account, your email address, your password information, your session and device identifiers, and the position, description, dates and other details of your readings.

We keep only anonymised measurement values from your readings: the fluorescence curve and the results calculated from it. We keep them to test and improve our calculations. They have no link to you, your account, your device, your meter, a place or a time, so they are no longer personal information.

Data Security

  • All communication between the App and our server is encrypted with HTTPS/TLS.
  • Your session identifier and device identifier are stored in the iOS Keychain.
  • Access to our server and data is limited to people who need it to run the service.

No method of transmission or storage is completely secure, but we work to protect your information.

Your Rights

Under data protection law, including the EU General Data Protection Regulation (GDPR), you have the right to:

  • Access the personal information we hold about you.
  • Correct inaccurate information.
  • Delete your information (see “Deleting Your Account”).
  • Receive your data in a portable format.
  • Object to or restrict certain processing.
  • Withdraw consent at any time, for example by turning off location access in iOS Settings. This does not affect processing that took place before.

To exercise these rights, email info@spectracrop.com. You also have the right to complain to a data protection authority. In Denmark this is Datatilsynet (www.datatilsynet.dk).

Permissions

  • Bluetooth: needed to connect to your SpectraCrop meter. You can turn it off in Settings → SpectraCrop, but the App then can’t download readings from the meter.
  • Location: optional, only while using the App (see section 3). You can change it at any time in Settings → SpectraCrop → Location.

Children

The App is not intended for children under 16, and we do not knowingly collect personal information from them. If we learn that we have, we will delete it.

Changes to This Policy

We may update this Privacy Policy. We will post the new version on our website and update the effective date above.
