Privacy

Short version: no account, no email, no tracking cookies; the public pages show one banner ad (see Advertising). What you type into the Flow Builder is used to write your plan and is not kept unless you save it to a Flow Locker.

What is kept

• The Flow Builder sends the form to the server (as a form post, so the business details are not in the page address or the web server’s access log) and writes the plan. It is not stored. The access log does record the pages visited and your IP address, which the hosting server keeps for a limited time.
• A Flow Locker keeps the flows you saved, its name and the dates it was made, changed and last opened. Its private key is never stored: only a one-way hash of it. Your browser keeps the key in a cookie that only this site can read.
• Daily limits keep a one-way hash of your IP address with a count for the day, deleted after 3 days.

What is never collected

No names of people beyond what you choose to type into a greeting, no emails, no card numbers, no recordings and no locations. No analytics services and no outside fonts. Apart from the banner ad on the public pages, described under Advertising, every file comes from this site; the ad tag also counts one page view per page as a daily total. “Hear it” uses your own browser’s speech voice; the text is not sent anywhere by this site.

Deleting

Delete a locker from the locker itself (type delete to confirm). Lockers not opened for 400 days are deleted automatically. Nightly database backups are deleted after 14 days.

Advertising

The public pages of Ninekey (home, the Flow Builder's blank worked example, Holidays, Guide and Pricing) show one banner ad from AdEngine (adengine.us), the small ad network run by WeldonPC, the company behind this site. For now the ads are for WeldonPC's own services. A flow you build (the answer page), a flow opened from your Flow Locker, setup sheets, Flow Locker pages, this page and the terms show no ad.

To show an ad, your browser loads a script from adengine.us, asks it for one banner, loads the banner image, and reports once that the page was viewed and once that the banner was shown. Like any website, adengine.us receives your IP address, your browser type and the address of this site with those requests. It is not sent anything you type into the Flow Builder.

• No cookies, no profile. AdEngine sets no cookies, gives you no ID and does not track you from site to site.
• How your IP address is used. adengine.us looks up the approximate city for your IP address in a location database kept on its own server (nothing is sent to anyone else), so that ads meant for one area are shown only there. It also uses the address to count each ad view or click only once and to leave out robots and WeldonPC's own office traffic. The address is not stored with the counts; the temporary entries made from it expire within six hours and are cleared from the server within two days.
• What is kept. Daily totals only: page views for this site, and views and clicks for each ad. The adengine.us web server also keeps a standard access log (IP address, time, address requested, referring site, browser) for security; it is deleted on a rolling schedule.
• Clicking an ad passes through adengine.us, which counts the click, and then opens the advertiser's site, which has its own privacy policy.
• Nothing about you is sold or shared.

Payments (later)

When paying opens, PayPal handles the payment. This site will keep only the subscription reference, plan and paid-until date, linked to the locker.
