  • 1. What is Yepzon and who is it meant for?

    Yepzon is an easy-to-use tracker and service with which you can track people, pets and objects. By attaching Yepzon anywhere you can track your target with an app for your smartphone, even on the other side of the world.

    Yepzon devices have a built-in SIM, GSM modem, and GPS receiver.

  • 2. What is the difference between ONE and Freedom devices?

    Yepzon ONE is a GPS tracker which has been designed specifically for tracking small children, pets and objects. The device is hung on the tracked person or object and it does not have a button, meaning control of the device happens fully through the mobile application. The technical information can be found on the Yepzon ONE product page.

    Yepzon Freedom is a personal alarm with GPS tracking which is meant for everyone from school age and up. In addition to the tracking function, by pressing the SOS button on the device, an alert can be sent from the Freedom device to the application, and the app will tell the location of the device that sent the alert. In practice, you can communicate from the Freedom to the application. The Freedom device includes different functions which can be changed depending on the use. The technical information can be found on the Yepzon Freedom product page.

  • 3. How much does Yepzon cost?

    Yepzon One - 3999 with one year free subscription
    Yepzon Freedom - 5999 with one year free subscription

  • 4. What is the cost/month after the free subscription is over?

    The monthly recurring cost is Rs 100/month

  • 5. How does Yepzon work?

    The user controls the Yepzon tracker with the Yepzon App® mobile application on which the user can see where the device is located and can track the device accurately.

    On the Settings of the app, the user can determine how often Yepzon connects to the server, in other words with which delay the tracking can be started. The shorter connection frequency (min. 1 min.) the quicker the location information can be accurately received. The connection frequency settings also affect the device’s battery life and data consumption. The longer connection frequency, the longer the battery life and less data is consumed.

  • 6. What kind of smartphone or tablet does Yepzon need?

    Yepzon can be connected to a smartphone or a tablet that fulfils the following requirements:

    • Windows Phone 8.1 + NFC (only Yepzon ONE)
    • iPhone 4S or newer (iOS 7.0 or newer + Bluetooth Smart (BT 4.0))
    • Android 4.3 or newer + NFC OR Bluetooth Smart (BT 4.0)

    In Windows Phone devices, Yepzon App uses the NFC function to connect Yepzon ONE tracker and the smartphone/tablet and in Android devices additionally also Bluetooth. In iOS devices, Yepzon ONE is connected through Bluetooth. In iOS and Android devices, Bluetooth is also used for Yepzon ONE’s nearby tracking.

    For Yepzon Freedom, connecting the device happens through a QR code in all iOS and Android phones that fulfill the requirements. Yepzon Freedom cannot be used with Windows Phones.

    The app may also be downloaded onto devices with do not fulfill the previously mentioned requirements, but in that case all features might not be in use. For example, if you have a WP device on which the app downloads but you cannot pair it because your device does not have the NFC feature, ask your family member or friend to make the pairing in their device and then share the control through email onto your own device. After you get the control, if you want to, you can remove their Yepzon permission.

  • 7. Where can I get the Yepzon App mobile application?

    Yepzon App can be found in Google’s, Windows Phone’s, and Apple’s app stores with the name Yepzon App. The app is free and no registration is needed.

    Using the app always requires a Yepzon device.

  • 8. Can I download the Yepzon App even if I don’t own a Yepzon tracker?

    The Yepzon App can be downloaded and started up on a compatible smartphone/tablet even if you did not own a Yepzon tracker. However, the app’s features cannot be used before you pair your phone with the Yepzon tracker or someone else shares the Yepzon tracker’s permission with you.

  • 9. How is the location information figured out and how long is it available?

    By default, the app shows the location information based on the GSM network’s base stations. Its accuracy ranges, depending on the place, from some hundred metres to a couple kilometres. In urban areas, the accuracy is usually better than in more sparsely populated areas or in the countryside.

    Accurate location information can be received by clicking the Track accurately-icon on the Yepzon App. Next time Yepzon gets in contact, it gets the information about the tracking request and starts GPS tracking. How much time getting the accurate location information depends on the connection frequency determined by the user. (see question 9).

    Even though the GPS receiver on the Yepzon device is very sensitive, the GPS location is not always available, for example, when indoors or in parking garages. In Yepzon ONE, Bluetooth helps with indoor tracking and in Yepzon Freedom it is done with Wi-Fi tracking technology.

    Based on one tracking request, Yepzon sends its location every 10 seconds for 3 minutes. The tracking request can be repeated as many times as needed.

    Yepzon is not meant for long-term, continuous tracking of targets.

  • 10. Connection frequency: How quickly will the location info be available?

    The user determines how often Yepzon is in contact with the app from the mobile app’s settings. This is called connection frequency. How quickly the user gets the location info depends on when the tracker has last checked the situation. The waiting time is the determined connection frequency at maximum.

    The connection frequency affects battery life and data consumption, so the user can decide for themselves, according to the purpose of use, how often the accurate location information should be available.

    On the app’s Settings, the connection frequency is specified separately for Moving and Resting modes. When Yepzon has been still for 30 minutes it goes automatically into Resting mode. When Yepzon is moved, it goes automatically into Moving mode. Sometime after tracking, Yepzon’s mode stays ‘moving’ even if the device was still.

    Example 1: The device’s connection frequency is 5 minutes. The last connection was at 12:00. The user taps the Track accurately icon at 12:01. Yepzon starts tracking after four minutes, at 12:05.

    Example 2: The connection frequency is 3 hours and the device is resting. The last connection was at 12:00. The user taps the Track accurately icon at 12:01. Tracking starts at 15:00 except if the device starts moving before that, in which case the tracking starts moving immediately.

  • 11. If I change the connection frequency, when will the new one come into effect?

    At the latest when Yepzon connects to the app as per the old settings. Changing the settings immediately can be done by connecting the device to the charger. This way Yepzon performs an extra connection to the app and the settings come into effect immediately.

  • 12. What is the accuracy of the location info given by Yepzon?

    To find out the tracker’s location, Yepzon uses three different methods of tracking:

    • Mobile phone base station location based tracking
    • GPS satellite tracking
    • Bluetooth Smart signal tracking (Yepzon ONE)
    • Wi-Fi indoor tracking (Yepzon Freedom)

    Yepzon chooses the optimal way to track independently. The accuracy of GPS tracking is 3 to 4 metres at its best. Notice that GPS tracking needs a connection to at least three satellites in order to work. For example, inside buildings the GPS signal is usually either too weak or none existent. In that case the next, more imprecise available tracking method is used, which is based on GSM support stations. In the city, its accuracy ranges from a couple hundred metres to a couple kilometres. In the countryside, where there are less support stations, the location accuracy can be even ten kilometres or more.

    Yepzon Freedom includes Wi-Fi indoor tracking, which makes getting more accurate location information possible, even on a room’s accuracy. Wi-Fi tracking uses the five strongest identified networks to estimate the device’s location. Yepzon Freedom recognizes nearby Wi-Fi signals automatically, so no login to these networks is necessary.

    The Yepzon ONE device has a blue bar on the bottom of the map which shows the strength of the Yepzon’s Bluetooth signal if you have an Android or iOS phone/tablet which supports Bluetooth Smart technology and the tracked Yepzon is within the Bluetooth signal’s range (around 50 metres in situations with no interference). By moving calmly in different directions while simultaneously keeping an eye on the bar it is possible to deduce where the Yepzon is.

  • 13. What is the difference between moving and sleeping modes?

    Yepzon goes automatically in resting mode after being still for 30 minutes and goes back to active mode when the device moves. Sometime after tracking the device’s mode will stay ‘moving’ even if the device was still. The only difference between the modes is that the user can define their connection frequencies, in other words how often Yepzon connects to the app, differently. By default, in moving mode the update frequency is every 5 minutes and in resting mode 6 hours.

    Note! Right after positioning, Yepzon’s status is “Moving” for 40 minutes no matter if it’s moving or not. This is because after positioning Yepzon connects server for 10 minutes within 1 minute intervals in order to enable a quick re-positioning. After that Yepzon connects server for next 30 minutes within regular Moving mode connection intervals, for the same reason.

  • 14. Does Yepzon’s tracking work indoors?

    Yepzon is primarily a GPS tracker, therefore location information can be received worldwide. Roofs and walls of buildings weaken the signal so much that GPS devices cannot usually give accurate location information indoors. However, Yepzon’s GPS receiver is extremely sensitive and it is possible for the device to get a signal indoors as well.

    The GPS location’s accuracy can be weaker indoors than outside. If the GPS signal is not found indoors immediately after the first tracking period (3min), it is advised to try again immediately, since calculating the location based on very weak signals is slow. Often the GPS location is found indoors after the second or third try.

    Yepzon Freedom includes Wi-Fi tracking which enables tracking indoors as well.

    Bluetooth technology helps with Yepzon ONE’s indoor tracking. If your iOS or Android smart device supports BT Smart and the Yepzon in tracking mode is inside the BT signal’s range, on the bottom on the map view a blue bar can be seen, the length of which corresponds to the strength of the signal. This can be used to help when heading for the lost Yepzon.

  • 15. Which maps does Yepzon use? Can the app use large-scale topographic maps?

    The Yepzon App uses the phone manufacturer’s own map (for example Google Maps on Android phones). The map can be viewed in satellite mode. How well the location can be seen in the terrain, depends on the clarity of the satellite photos. The clarity differs considerably between phone manufacturers and districts.

    For the time being, third party maps cannot be used with Yepzon.

  • 16. How do Freedom tracker’s modes differ from each other?

    Freedom has three different modes which can be changed depending on the purpose of use. In the quick tracking mode, the device is constantly in online mode and can be tracked immediately with the app. This setting uses less data but more battery. The power save mode is the default setting on the device and the device works in the same way as ONE. A short delay to an accurate location uses more battery and data, whereas a longer tracking delay uses less battery and data. SOS only mode is meant for the device to be able to be tracked only by sending an SOS alarm. At other times the device is offline and does not even give a rough location. This means the device cannot be found with the app, only the battery life is visible. After a necessary SOS alert the device goes into power save mode, so that the device can be tracked on the app.

  • 17. How does Freedom’s SOS alarm work?

    Freedom sends an alert to the app by pressing the device’s SOS button quickly three times in a row. In this case, all the people following the device get the alert. At the same time, the device is automatically tracked and the tracking lasts for 5 minutes or until the SOS alert is acknowledged on the app.

    Optionally, on the app’s Settings, an alarm sound can also be put into the Yepzon Freedom device itself, in which case by pressing the SOS button, in addition to the app alert, the Yepzon device will also start an alert.

    The SOS alert works on all of the app’s Mode menu’s modes in the same way.

  • 18. Can anyone track my child with Yepzon?


    The person who connects a new Yepzon to their smartphone first will be the first user of the Yepzon in question. If the already equipped Yepzon is trying to be connected with another smartphone, a notification will pop up saying the pairing cannot be done since this Yepzon already has a user, and advising them to ask to give their permission.

    A Yepzon’s first user can give the permission of the Yepzon they control to other users. This means your child can only be tracked by the people who have been given permission to this Yepzon. All users

    • can give permission
    • can see who or which device has permission
    • can remove permission from each other
  • 19. How is permission given?

    In Yepzon’s Settings there is the Manage permissions setting where permission can be given. After that, follow the instructions on the screen. The method of sharing depends on the operating system, that is to say that Windows Phone, Android, and iOS each offer different options to send the permission giving link. We recommend email, because it works the best between different operating systems. This link is active for 24 hours. The link will stop working if the sender’s permission is removed.

  • 20. How is Yepzon charged and how long does the charging take?

    Under Yepzon tracker’s rubber plug there is a micro USB plug with which the tracker can be connected to a charger or, for example, a computer’s USB port.

    Charging an empty battery takes around 2.5 hours. During the charging process, the battery’s mode is shown as ‘Charging’. The charging is complete when the text is replaced with the number 100%. If Yepzon is disconnected from the charger in the middle of charging, the battery life number might drop fast since the battery has not been fully charged.

    It is recommended to charge Yepzon’s battery once a month but at least every three months, even if the device is not in use. If Yepzon is left uncharged for long periods of time, the battery might drain and cause a malfunction.

  • 21. How long is Yepzon’s battery life?

    With the default settings and normal use, the battery lasts usually around 1 to 2 weeks. Depending on the settings, the battery can last for even several weeks. If the tracker only connects, for example, once a day (example: boats), the battery life can be months. In this case, it is good to remember that the location information is received based on the connection frequency.

    The Yepzon Freedom device can be used in three different ways: in quick tracking mode, power save mode, and SOS mode. The device’s battery life depends on the chosen mode; in quick tracking mode, the battery lasts usually for 1 to 2 days, whereas in SOS mode it can last for weeks.

  • 22. How can I affect the battery life?

    You can affect the battery life by changing Yepzon’s resting mode and moving mode’s connection frequency. Fewer connections means better battery life and less data consumption.

    Also, whether or not the device is still (resting mode) or moving (active mode) has an impact on the battery life. Every tracking uses the battery a little.

    Freezing temperatures shorten the battery life.

  • 23. Can the pairing be cancelled?

    Yes. Yepzon’s pairings can be made and cancelled, in other words the access rights can be added and deleted as necessary. Deleting happens on the app’s Users and Delete user.

    All users can also delete other users’ access rights. Note that the access rights can only be retrieved by another user sharing them. After deleting the last user, the Yepzon can again be paired with a phone like a new device.

    The access rights to the Yepzon app are installation-specific. If you uninstall the Yepzon app, the pairing still remains, in which case you can re-equip the device only with the reset link. It is strongly recommended to create a reset link to email on the app’s Settings, where the device can be reinstalled if needed.

  • 24. Does Yepzon work in the cold?

    Yes, but the device’s lithium ion battery’s powering ability weakens considerably the colder it gets. This is typical for all small electronics. Charging the battery is not possible for safety reasons in sub-zero temperatures.

  • 25. What if I lose my phone?

    For safety reasons, Yepzon’s control should be shared with at least one other person in addition to the first user. This way the other user can share the device’s access rights on the first user’s new phone.

    It is strongly recommended to create a reset link to email when equipping the device. It can be done on the app’s Settings, and with it, the device can be reinstalled if needed, if the phone gets lost or the app is deleted. The reset link comes as an email message, which has a link by which you can click on and reset the Yepzon back to its factory settings and it can be paired again with a new phone.

    The reset link is functional as long as the user that ordered the link still has that particular Yepzon’s access rights. If the access rights of the person that ordered the link are removed, their reset link will also stop working.

  • 26. How many users can follow one Yepzon® tracker?

    No upper limit.

  • 27. How many Yepzon® trackers can one phone follow?

    No upper limit.

  • 28. Does the first user have more rights than the next ones?

    No. All users are equal.

  • 29. Is it safe to keep a device that sends radio frequency with me?

    The amount of electromagnetic radiation Yepzon transmits is comparable to a cell phone. When using it, it is advised to follow the recommendations of authorities and to use common sense. For example, pacemaker users should not carry Yepzon around their neck or in their chest pocket, just like a cell phone should not be carried.

    Yepzon’s SAR value is 1.46 W/kg. It falls below both the EU’s (2.0 W/kg @10g) And the United States’ (1.6 W/kg @1g) threshold values set by authorities regarding radiation absorbing into body, the minimum distance to body being 5mm.

  • 30. Why doesn’t the tracker have an off-switch? Can the tracker be turned off?

    For the ease of use. The carrier of the tracker does not have to pay any attention to the device. The carrier also cannot turn the device off accidentally or on purpose.

    The device can be turned off on the mobile application. For example, during a flight turning it off is essential for safety reasons. After turning it off, the device requires connection to the charger or needs to touch a phone that supports NFC (not in use in the U.S.). Yepzon’s NFC ID is located under the device’s back panel, above the rubber plug.

  • 31. How much data does Yepzon use?

    A new Yepzon device incudes 5MB worth of free data which corresponds to around 1 month of use with the default settings. The biggest effect on data consumption is the connection frequency of the Moving mode.


    • example 1: device moves 2h in a day, connection frequency 5min/6h, tracked 30 times per month -> consumes 1MB/month
    • example 2: device moves 12h in a day, connection frequency 5min/6h, located 300 times (!) per month -> consumes 9MB/month
    • example 3: device moves 6h in a day, connection frequency 1min/6h, located 30 times per month -> consumes 9MB/month


    • In power save mode (default) works like Yepzon ONE, see above.
    • In quick tracking mode (mode 1) very little data is used except if a lot of tracking is done. Note! Highest battery consumption.
    • In SOS only mode (mode 3) data is not used at all except if SOS button is pushed.
  • 32. Yepzon has turned itself off and does not turn back on again. What should I do?

    Any software might temporarily freeze for a variety of reasons. In some cases, your Yepzon might be out of power even if according to the app it should have power.

    In both cases connecting Yepzon to a charger helps.

    If the Data Tank is empty, Yepzon turns off until more data is bought.

  • 33. Does the Yepzon app collect user information?

    sing the device and downloading the app do not require registration or passwords. Hence, using the device does not require giving out contact information since Yepzon does not save user identification information. The IMEI code on the device functions as ID for example when dealing with technical questions.

    A monthly charged plan requires that a login is created (see terms & conditions of use).
