For privacy information regarding this website, please see the “Privacy & Cookies” menu at the bottom of this page.
The developer of this app values his privacy highly, and by extension the privacy of users of the app.
The developer therefore does not now, and will not collect or use any information through usage of the app.
The app does not use or store any personal information, only numbers used in calculations.
The app does not request or receive data from any server, other device or entity.
The app does not collect data for the purpose of retransmitting it to the developer or any third party. All data entered by the user is normally stored only in memory and on the device running the app.
Under some circumstances, described below, some information may get backed-up to the iCloud service. This can be enabled or disabled by the user. Please read the following carefully.
Recording and storage of timestamped altitude data
Timestamped altitude data can be recorded and stored in a text file on the device, if explicitly enabled by the user. Data is recorded in a text file. An entry is added every time altitude changes by at least one foot. An example of recorded information is shown below:
2020-03-24;13:40:48;UTC; press.alt.(ft)=;2511; alt.setting(InHg)=;29.92
2020-03-24;13:40:54;UTC; press.alt.(ft)=;2510; alt.setting(InHg)=;29.92
2020-03-24;13:41:08;UTC; press.alt.(ft)=;2509; alt.setting(InHg)=;29.92
Display and recording of altitude data is controlled via the Settings app.
Recording requires all following conditions to be met:
1) Fitness Tracking, under Settings – Privacy – Motion & Fitness is enabled;
2) a barometric sensor is available on the device;
3) the user has enabled the display of altimeter data, and
4) the user has enabled recording of altimeter data.
Recording of this data is disabled by default.
Recording can be disabled by the user at anytime.
Recorded information can be deleted by the user at any time.
Disabling recording, or deleting recorded information has no impact on the other functions of the app.
NO GEOGRAPHICAL LOCATION INFORMATION IS RECORDED. HOWEVER, IT MAY BE POSSIBLE TO INFER SOMETHING ABOUT THE USER’S LOCATION BASED ON TIME AND ALTITUDE READINGS CONTAINED IN THE RECORDED DATA.
If this is undesirable, please ensure you do not enable the recording feature, and delete the recorded file, using the Files app.
If data is recorded, it is stored in unencrypted form, and may get backed up to Apple’s iCloud service if the user has enabled iCloud backups.
