Revenue (Textual)
Credits, description	If a user purchases Zedge Credits (ranging from 500 credits for $0.99 to 14,000 credits for $19.99), Google Play or iTunes retains 30% of the purchase price as its fee. When a user purchases Zedge Premium content, the artist or brand receives 70% of the actual value of the Zedge Credits used to buy the content item ("Royalty Payment") and the Company receives the remaining 30%, which is recognized as Other Revenue. Some of the Zedge Premium content is available for print on demand merchandise, including phone cases and tee shirts fulfilled through third party vendors. When a user purchases a print-on-demand item the artist or brand is paid 70% of the net profit, after accounting for cost-of-goods sold, shipping and handling, credit card processing, and other direct expenses, and the Company recognizes Other Revenue in the amount of the remaining 30%.
Royalty payments, description	The Company makes Royalty Payments to the artists and brands within sixty (60) days after the end of each calendar quarter. If the quarterly royalty amount is less than two hundred dollars ($200), the Company may defer payment to a later period in which the artist or brand surpasses the $200 threshold. The artist or brand forfeits any accrued royalty amounts below the $200 threshold upon expiration or termination of the artist's license agreement with the Company. This provision will become effective on the first anniversary for all existing license agreements and for all new license agreements entered into on or after November 1, 2018. Additionally, the Company has established a minimum threshold of twenty-five dollars ($25) in accrued Royalty Payments in order for an artist or brand to maintain its license agreement. Accordingly, if an artist hasn't generated a minimum of $25 in accrued Royalty Payments amount in a year, the Company may deduct up to $25 from the artist's accrued Royalty Payment account.
