 ## Project history
 
 _OpenTracks_ is based upon Google _My Tracks app_ ([code](https://code.google.com/archive/p/mytracks/)).
-Initially, _My Tracks_ was initially released by Google in 2010 as [open-source software](http://google-latlong.blogspot.fr/2010/05/code-for-my-tracks-is-now-yours.html).
+_My Tracks_ was initially released by Google in 2010 as [open-source software](http://google-latlong.blogspot.fr/2010/05/code-for-my-tracks-is-now-yours.html).
 In 2016, [Google decided to discontinue](https://support.google.com/maps/answer/6333516) _My Tracks_ and stopped distributing it via the Google Play store in April 2016.
 Then [Plonk42](https://github.com/plonk42) conducted some maintenance work until 2016, so _My Tracks_ could still be used (based upon version _Google's MyTracks_ version 2.0.6).
 Plonk42's version is available [here](https://github.com/Plonk42/mytracks).

+    <string name="help_track_export_title">Como posso exportar/compartilhar trilhas gravadas\?</string>
+    <string name="help_track_export_content"> As trilhas podem ser exportadas das configurações como KMZ, KML ou GPX. KMZ/KML todos os dados; Localizações apenas GPX. As trilhas compartilhadas por meio do <i>ícone de compartilhamento</i> são compartilhadas como KMZ. </string>
+    <string name="help_track_map_content"> Utilize o pequeno ícone do mapa.
+\n a) (actualizações ao vivo) Instalar <a href="https://github.com/OpenTracksApp/OSMDashboard">OSMDashboard</a>. Fornece mapas online ou offline através de <a href="https://www.openstreetmap.org">OpenStreetMap</a>.
+\n Na verdade, o OSMDashboard é uma aplicação separada que só pode aceder (temporariamente) aos dados da(s) faixa(s) que vão ser mostrados.
+\n b) Através de uma aplicação de mapa normal (por exemplo, <a href="http://osmand.net/">OsmAnd</a> e <a href="https://maps.me/">MAPS.ME</a>). Estas aplicações precisam de suportar o formato de ficheiro KMZ (apenas locais e timestamps). De facto, uma aplicação precisa de suportar <i>ACTION_VIEW</i> com MIME <i>application/vnd.google-earth.kmz</i>. </string>
+    <string name="help_recording_content">OpenTracks usa o sensor GPS do aparelho para registar a localização continuamente. Se o aparelho GPS relatar dados imprecisos (por exemplo, localização, velocidade, elevação), o OpenTracks não pode fazer nada a respeito.</string>
+    <string name="help_data_storage_title">Como o OpenTracks armazena dados do sensor\?</string>
+    <string name="help_data_storage_content"> Os dados do sensor são armazenados por local registado. Em termos de sensor de frequência cardíaca, isso significa que apenas <i>uma</i> medição de frequência cardíaca é armazenada por local.

+\n a) verificar se o GPS está activado,
+\n b) melhorar a recepção GPS (por exemplo, ir para o exterior),
+\n c) verificar com <a href="https://f-droid.org/en/packages/com.android.gpstest.osmdroid/">GPSTest</a> app, e
+\n d) desactivar a poupança de energia.
