+               <description>&lt;p&gt;A few days ago, I wondered if there are any privacy respecting
+health monitors and/or fitness trackers available for sale these days.
+I would like to buy one, but do not want to share my personal data
+with strangers, nor be forced to have a mobile phone to get data out
+of the unit.  I&#39;ve received some ideas, and would like to share them
+with you.
+
+One interesting data point was a pointer to a Free Software app for
+Android called
+&lt;a href=&quot;https://github.com/Freeyourgadget/Gadgetbridge/&quot;&gt;Gadgetbridge&lt;/a&gt;.
+It provide cloudless collection and storing of data from a variety of
+trackers.  Its
+&lt;a href=&quot;https://github.com/Freeyourgadget/Gadgetbridge/#supported-devices&quot;&gt;list
+of supported devices&lt;/a&gt; is a good indicator for units where the
+protocol is fairly open, as it is obviously being handled by Free
+Software.  Other units are reportedly encrypting the collected
+information with their own public key, making sure only the vendor
+cloud service is able to extract data from the unit.  The people
+contacting me about it said they were using
+&lt;a href=&quot;https://us.amazfit.com/shop/bip?variant=336750&quot;&gt;Amazfit
+Bip&lt;/a&gt; and
+&lt;a href=&quot;http://www.xiaomimi6phone.com/xiaomi-mi-band-3-features-release-date-rumors/&quot;&gt;Xiaomi
+Band 3&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;I also got a suggestion to look at some of the units from Garmin.
+I was told their GPS watches can be connected via USB and show up as a
+USB storage device with
+&lt;a href=&quot;https://www.gpsbabel.org/htmldoc-development/fmt_garmin_fit.html&quot;&gt;Garmin
+FIT files&lt;/a&gt; containing the collected measurements.  While
+proprietary, FIT files apparently can be read at least by
+&lt;a href=&quot;https://www.gpsbabel.org&quot;&gt;GPSBabel&lt;/a&gt; and the
+&lt;a href=&quot;https://apps.nextcloud.com/apps/gpxpod&quot;&gt;GpxPod&lt;/a&gt; Nextcloud
+app.  It is unclear to me if they can read step count and heart rate
+data.  The person I talked to was using a Garmin
+&lt;a href=&quot;https://buy.garmin.com/en-US/US/p/564291&quot;&gt;Garmin Forerunner
+935&lt;/a&gt;, which is a fairly expensive unit.  I doubt it is worth it for
+a unit where the vendor clearly is trying its best to move from open
+to closed systems.  I still remember when Garmin dropped NMEA support
+in its GPSes.&lt;/p&gt;
+
+&lt;p&gt;A final idea was to build ones own unit, perhaps by basing it on a
+wearable hardware platforms like
+&lt;a href=&quot;https://learn.adafruit.com/flora-geo-watch&quot;&gt;the Flora Geo
+Watch&lt;/a&gt;.  Sound like fun, but I had more money than time to spend on
+the topic, so I suspect it will have to wait for another time.&lt;/p&gt;
+
+&lt;p&gt;While I was working on tracking down links, I came across an
+inspiring TED talk by Dave Debronkart about
+&lt;a href=&quot;https://archive.org/details/DavedeBronkart_2010X&quot;&gt;being a
+e-patient&lt;/a&gt;, and discovered the web site
+&lt;a href=&quot;https://participatorymedicine.org/epatients/&quot;&gt;Participatory
+Medicine&lt;/a&gt;.  If you too want to track your own health and fitness
+without having information about your private life floating around on
+computers owned by others, I recommend checking it out.&lt;/p&gt;
+
+&lt;p&gt;As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address
+&lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.&lt;/p&gt;
