Deepstash is a scam and they will steal…
Deepstash is a scam and they will steal your money. I started a trial subscription to Deepstash a few months ago. I cancelled the free trial well before the trial ended. I was just charged $49.95 well after the cessation of my trial. There are so many people sharing stories that are no different than mine. It is egregious behavior on the part of the application, and the people behind it.
I immediately contacted my bank to file a fraudulent charge and opened a fraud/misleading charges ticket against this company. I have also reported the app to Apple Support. Deepstash app and the people behind it need to be held accountable for shady business practices. Stay away from this horrendous “service” - $50 is a lot of money to most people and I hope nobody has to go through what I, and many before me have experienced.

Thank you for sharing your feedback. We’re sorry to hear about your experience.
Based on the price you mentioned, this particular plan does not include a trial period, which suggests there may be a misunderstanding or that multiple accounts could be involved. It is possible that a trial was canceled on one account, while another subscription remained active and renewed accordingly.
To help us investigate this further and locate the specific charge you mentioned, please contact our support team directly at help@deepstash.com and include reference number MK23828937. Once we have this information, we can provide a clear breakdown and assist you accordingly.
We look forward to resolving this matter with you.
Best regards,
Deepstash Team
What made this experience great was…
What made this experience great was having access to countless of different topics that get straight to the point or meaningful information that you can collect from what you read. What this company is doing well is the willingness to provide the controversial but important books for us to read such as “1984” or “The 47 Laws of Power”.

Naturally replaces social media habits
I like the format and how it naturally replaces social media habits, I would have liked the information to be a bit more bite-sized, but in saying that it is still effective in its purpose. Thank you.

Free Trial Scam
I signed up for the free trial, but was not notified before this trial ended about the yearly subscription rate, and I was charged anyway. Not worth it! Mindless scrolling on YouTube does not cost $70 a year, and I'm perfectly fine with that!

Hi Chris,
Thank you for sharing your feedback, and we’re sorry to hear about your experience.
We’d like to clarify that we sent a reminder two days before the charge via push notification, informing you that your free trial would convert into a paid subscription. It is also available in the app’s notification history.
That said, we completely understand your concerns and our support team has contacted you directly so we can better assist and hopefully find a solution together.
Thank you again for giving Deepstash a try.

Hi Vishruth,
Thank you for taking the time to share your feedback.
We’re really happy to hear that you enjoy the app overall and we’re sorry for the confusion regarding the question flow.
We’d like to clarify that this experience was intentionally not designed as a traditional test where one answer is “correct” and the other is “wrong.” The purpose of those questions is meant to feel more reflective and personal, encouraging deeper thinking and individual interpretation rather than a standard A/B quiz format.
That said, we completely understand how the current experience could make it seem like answer “A” is always the expected choice, and we appreciate you pointing this out. We’ll absolutely share your feedback with the team so we can make the flow much clearer and more intuitive moving forward.
We sincerely apologize again if this part of the experience felt unclear, and we truly appreciate your support and the positive comments about the rest of the app. We hope you’ll give us another chance in the future.
Best regards,
Deepstash Team

Cancellation Request
Support team took time to explain the difference between Free account and Free trial period for Pro account. While it was very unclear while downloading the app (and also concerning given the other negative reviews), their explanation allowed me to understand their process. They assured me that there is no automatic upgrade to a paid Pro subscription. I'm grateful for their support.

I cannot recommend this company.
I cannot recommend this company.
Subscription payments are processed outside of the Google Play Store's secure environment. Consequently, when my subscription unexpectedly renewed, my request for a refund, submitted shortly after the payment was processed, was denied.
Under similar circumstances within the Play Store, an immediate refund would typically be issued.
I am currently out of pocket by $85 NZD. I will update this review should a refund be provided

I purchased Deepstash
I purchased Deepstash. Gave it a legit try and decided it wasn’t for me. Even though there was a money back guarantee, they are refusing to refund because I didn’t spend enough time on the app. Totally ridiculous they wouldn’t honor the money back guarantee. Don’t bother with this app/ company.

A complete scam - go nowhere near
Update after their reply to my review here; still no refund or ‘goodwill gesture’ and no replies to email.
A complete scam. Downloaded the app, didn’t use it. I keep an eye on subscriptions via my Apple account and nothing was on there about Deepstash - which was on the terms of service that was on the app - then found my card was charged. Immediately emailed for a refund and got one email to say it wasn’t going to happen and they refused to respond to the rest. An absolute disgrace of a company.

We are sorry to hear about your experience, but we would like to clarify that the information in this review is not accurate.
Our support team responded to your email very shortly after it was received, and we have continued replying to your follow up messages as well. Most recently, our team contacted you again with a proposed resolution and goodwill offer in an attempt to resolve the situation fairly.
We also want to clarify that subscriptions started directly through our website will not appear under Apple subscriptions, as only App Store subscriptions are managed there.
We always do our best to assist our users respectfully and promptly, and we remain open to resolving this matter together through our ongoing email communication.

Horrible customer service
I came on here because I recently was charged for a subscription I cancelled.
Then come to find out a lot of other customers have had similar issues with this company as well. I contacted them after seeing a charge that I wasn't aware of and they denied me a refund because of their “policy”. Highly unsatisfied with the service.

Unexpected Charge and No Response From Support
I was charged unexpectedly for a Deepstash subscription without receiving the renewal reminder that was promised. I contacted support within 14 days because I did not like the app and wanted a full refund, but I still have not received any reply to my email.
The app itself was not for me, which is fine, but the customer support experience has been frustrating. It is already difficult to find a support contact, and now there is no response at all.
I would like Deepstash to respond to my email and process my refund request.

Shady business
Awful company with shady business practices. I tried to cancel my subscription in which I thought went through but was charged anyways. I went to the app to do it again and realized there is multiple pages you have to click cancel on and not just once. Contacted Deepstash just after being respectful and explained that to them. They would not refund me and only offered me a complimentary upgrade on a yearly subscription instead. Shady business practices with no customer support. Planned to use the app in the future and now will not be back.
