The apps are published by Double Support ("we") as "Zyntra by Double Support": Zyntra (com.doublesupport.zyntra_app) and Flowrica (com.doublesupport.flowrica_app). Our website has its own privacy policy; this page is only about the apps.
Who the apps are for
The apps are work tools for people whose company uses Zyntra OS. There is no sign-up in the apps: your company opens your account, and you sign in with it. The apps are made for adults at work and are not meant for children.
Where your data goes
- Your company's own Zyntra site. What you send from the app goes only to the Zyntra site of the company you signed in to (for example yourcompany.gozyntra.com). Your company decides who sees it there, by each person's rights, exactly as in Zyntra OS on the computer.
- Finding your company's site. When you sign in with your email, the app first asks our Control Center which company's site that email belongs to. Only the email is sent for this, and only the site's address comes back.
- Flowrica Advance, only when your company switched it on. Flowrica answers from your company's own records. If your company turned on Flowrica Advance, a question you ask Flowrica, or a document or photo you give her to read, is sent from your company's site to Google's service to be read, on your company's own key and within the monthly limit your company sets. When Flowrica Advance is off, nothing is sent there.
- Calls. A call you make or answer in Flowrica through your company's Call Center is carried by the phone service your company connected to its Zyntra site.
We do not sell your data and we do not show ads. The apps carry no advertising or tracking tools.
What each app reads on your phone
Each app asks the phone's own permission before it uses any of these, and only when you use the feature that needs it. You can say no, or change it later in your phone's settings; the rest of the app keeps working.
- Camera. Zyntra: to scan the sign-in and check-in codes, to photograph a receipt for an expense claim or a customer visit, and to read an item's barcode. Flowrica: to photograph receipts, cheques and statements, to read barcodes, and to scan QR codes such as the pairing code on your computer. A photo is sent to your company's site only when you send it.
- Microphone. Flowrica only: when you speak to Flowrica, and for calls you make or answer through your company's Call Center. What you say to Flowrica is turned into text on the phone, and only the text is sent. Zyntra does not use the microphone.
- Location. Zyntra: when you check in or check out at a customer's place on a field visit, and to show the customers near you when you start a visit. Flowrica: to order your visits from where you are when you ask her to plan your day, and to keep the place with a quote your customer signs on the phone. Your location is read only at that moment, never in the background.
- Contacts. Flowrica only, with your permission: to fill a new customer from the one contact you pick in the phone's own contact picker. Only that contact's name, company, phone and email leave the phone. Zyntra does not read your contacts.
- Calendar. Flowrica, with your permission: reads today's events on the phone to put your day in order when you ask; they are shown to you on the phone and are not sent. Zyntra, with your permission: adds your approved leaves and work shifts to your phone's calendar and removes a leave you withdraw; nothing is read from it.
- Photos and files. Both apps: a photo you choose, for example a receipt. Flowrica also takes a file you share into her from another app. Only what you choose is sent.
Sign-in data
You sign in with a link sent to your work email, with your email and password, with your Microsoft work account when your company set it up, or by scanning a code from Zyntra OS on your computer. Your email and password go only to your company's site; the Microsoft sign-in opens in the phone's browser, on Microsoft's own page. After you sign in, the app keeps its sign-in keys in the phone's protected storage. The app also makes a random number for this phone, named only "Android phone" or "iPhone", so that your company's site can list your devices and you can sign a phone out from Zyntra OS. Signing out removes the sign-in keys from the phone.
Notifications
When notifications are turned on, the app gives your company's site this phone's notification address (a push token), so the site can tell you, for example, that a request was decided or an announcement arrived. A notification carries only a kind and a number, never an amount or a name; the app opens and reads the rest from your company's site under your own rights.
What you send through the apps
What you type or choose in the app is sent to your company's site to do what you asked: for example a leave request, an expense claim with its receipt, a check-in, your phone, address and emergency contact in My Space, a new customer, an invoice, a payment, or a quote your customer signs on the phone. It is kept there as the same record you would make in Zyntra OS on the computer. Your company's site sends the app only what your rights allow you to see, such as your payslips, your leave balance and your custody, or, for a manager, the figures Flowrica shows.
What stays on the phone
Besides the sign-in keys, the app keeps a few settings, such as the language and the company you work in. If you are offline, Zyntra keeps a request you made on the phone and sends it when you are back online; you can remove it before it is sent. On Android, Flowrica's home-screen widget keeps a few of today's figures on the phone and refreshes them about once an hour. Uninstalling the app removes everything it kept on the phone.
Security
The apps talk to your company's site only over an encrypted connection (HTTPS).
How long data is kept, and deleting it
Your records are your company's records. They are kept on your company's Zyntra site for as long as your company keeps them, under its own rules, and a record that is removed is archived by those same rules. To see your data, take a copy of it, correct it or ask for it to be deleted, ask your company — the administrator of your Zyntra site — or write to us at [email protected]: we pass your request to your company and help it carry it out.
Changes to this policy
If an app starts to read something new, we update this page and its date before that version of the app is published.
