This Privacy Policy describes how BASELog ("the App", "we", "us", "our") handles your information. We are committed to protecting your privacy and being transparent about our data practices.
01Data we do not collect
We want to be clear about what we do NOT do:
- We do not operate any servers, databases, or cloud infrastructure that stores your data.
- We do not collect, access, view, analyze, or process your personal data.
- We do not use any analytics, tracking, or telemetry frameworks.
- We do not use any crash reporting services.
- We do not serve advertisements.
- We do not sell, share, rent, or trade your data with any third party.
- We do not create user profiles or track your behavior.
- We do not use cookies or similar tracking technologies.
02Data you create in the App
When you use BASELog, you create and store the following types of data locally on your device:
Jump and Flight Records
- Jump/flight date, time, and duration
- Jump numbers and sport type
- Exit altitude, comments, and session details
- Performance notes and coaching indicators
GPS Track Data
- GPS tracks imported from external devices (FlySight, phone GPS, etc.)
- Calculated performance metrics: speed, altitude, freefall time, deployment altitude, canopy time, glide ratio, G-force, distance measurements
- Track timestamps and GPS signal quality indicators
Exit and Location Data
- Exit/site names and descriptions
- Geographic coordinates (latitude, longitude)
- Elevation, height, and approach information
- Location metadata: town, region, country, timezone
Equipment Data
- Gear names, types, and brands
- Serial numbers and dates of manufacture
- Equipment size, weight, and configuration
- Service and maintenance records (dates, service provider names, notes)
Incident Data
- Incident type classification
- Injury status (yes/no)
- Outcome classification
Personal Identifiers
- A locally generated unique user identifier (UUID) used to identify data ownership in exports and shared exit records
- This UUID is generated on your device and is not linked to your name, email, Apple ID, or any other personal identifier
03Where your data is stored
On your device
All data is stored in a local Core Data database on your iOS device. This data is protected by your device's security features, including device passcode, Face ID, or Touch ID.
iCloud (optional)
If you have iCloud enabled on your device, BASELog uses Apple's CloudKit service to synchronize your data across your Apple devices signed into the same Apple ID. This synchronization:
- Is managed entirely by Apple's infrastructure
- Is protected by Apple's encryption and security measures
- Is governed by Apple's Privacy Policy
- Can be disabled by turning off iCloud for BASELog in your device's Settings
- We have no access to your iCloud data
Widget data
If you use BASELog widgets on your home screen, a small subset of your data (recent jump statistics, last jump details) is stored in a shared container on your device accessible only by the App and its widget extension. This data never leaves your device.
Shared app container
If you use the Activitough companion app, GPS track files may be exchanged between the two apps via a shared container on your device. This exchange occurs entirely locally and involves no network transmission.
04Third-party services
BASELog makes minimal use of external services. When it does, the interaction is limited and transparent:
Open-Meteo Elevation API
- When used: Only when you explicitly request elevation data for an exit location (e.g., tapping on a map or entering coordinates).
- Data sent: Geographic coordinates (latitude and longitude) only.
- Data received: Elevation value for the specified coordinates.
- No personal data is transmitted. No authentication, cookies, or device identifiers are sent.
- Open-Meteo is a free, open-source API. For their privacy practices, visit open-meteo.com.
Apple CloudKit (iCloud)
- When used: Automatically, if iCloud is enabled for BASELog on your device.
- Data transmitted: Your entire BASELog database for synchronization across your devices.
- Managed by: Apple, under their privacy policy and terms of service.
- Our access: None. We cannot access your CloudKit data.
Apple Core Spotlight
- When used: Automatically, to allow you to find your jumps, exits, and gear via system search (Spotlight).
- Data indexed: Jump numbers, exit names, gear names, dates, locations.
- Storage: The Spotlight index is stored locally on your device and managed by iOS.
- Our access: None.
Instagram (optional, user-initiated)
- When used: Only when you explicitly choose to share a jump card to Instagram Stories.
- Data shared: A rendered image of your jump performance card and an optional deep link back to BASELog.
- Mechanism: Data is passed via the device's pasteboard to the Instagram app. No network request is made by BASELog during this process.
FlySight 2 GPS logger (Bluetooth)
- When used: Only when you explicitly connect to a FlySight 2 device.
- Data exchanged: GPS track files are downloaded from the FlySight device to your iPhone via Bluetooth Low Energy (BLE).
- No data is transmitted to any server. The communication is direct between your device and the FlySight unit.
05Data export and sharing
BASELog provides several ways for you to export your data:
- Full Logbook Export (JSON): Exports all your data including jumps, exits, gear, incidents, GPS tracks, and services. The export file includes your locally generated UUID in the metadata.
- Exit Export (JSON): Exports selected exit locations with associated jump data.
- GPS Track Export (GPX): Exports GPS tracks in the standard GPX format.
- Siri Shortcuts: You can configure Siri Shortcuts to trigger a logbook export.
All exports are initiated by you and saved to a location of your choosing (Files app, iCloud Drive, or shared via the system share sheet). We have no visibility into when or how you export your data.
06Data retention and deletion
- Your control: You have full control over your data at all times. You can delete individual records (jumps, exits, gear) or clear all data from within the App's Settings.
- No automatic deletion: We do not automatically delete any of your data. Records persist until you choose to remove them.
- iCloud deletion: If you delete data in the App with iCloud sync enabled, the deletion propagates to all your synced devices. If you disable iCloud sync, a local copy of your data remains on each device.
- App deletion: If you delete the App from your device, the local database is removed. If iCloud sync was enabled, your data may still exist in your iCloud account until you remove it from iCloud storage.
07Data security
- All data stored on your device is protected by iOS security features, including hardware encryption.
- iCloud data is protected by Apple's encryption (in transit and at rest).
- The App does not implement its own encryption layer because it relies on the robust security provided by iOS and iCloud.
- Bluetooth communication with FlySight devices uses the BLE security features provided by iOS.
08Children's privacy
BASELog is not intended for use by children under the age of 17. The sports documented by this App (BASE jumping, skydiving, paragliding, speed flying, speed riding, wind tunnel flying) are extreme activities that require appropriate age, training, and certification. We do not knowingly collect data from children.
09Your rights
Depending on your jurisdiction, you may have the following rights regarding your data:
- Access: You can view all your data within the App at any time.
- Portability: You can export all your data in open formats (JSON, GPX) at any time.
- Deletion: You can delete any or all of your data at any time from within the App.
- Rectification: You can edit any record at any time.
Because we do not collect or store your data on our systems, many traditional data subject rights (such as requesting data from a company) do not apply in the conventional sense. Your data is always under your control, on your device and in your iCloud account.
10International data
If you use iCloud sync, your data may be stored in Apple's data centers located in various countries. Apple's data handling practices, including international data transfer safeguards, are described in Apple's Privacy Policy.
We do not independently transfer your data across borders. The only cross-border data flow is the Open-Meteo API request (geographic coordinates only), which is processed by Open-Meteo's infrastructure.
11Changes to this policy
We may update this Privacy Policy from time to time. Changes will be made available within the App. The "Last Updated" date at the top of this policy indicates when the most recent changes were made. Your continued use of the App after changes are posted constitutes acceptance of the updated policy.
