I need to implement a system where when the user install my app for the first time, he has 3 month of free use.
After three month the app has to show in-app purchase options.
I need to avoid that if the user remove and reinstall app, he can again use three month of free use.
I thought to use InApp purchase (a free, Non-Consumable item) to achieve my goal.
Using 'Non-Consumable' I have that 'SKPaymentTransaction *originalTransaction' contains the date of original transaction, so I can know If 3 month are expired or not and if the user reinstall or install the app in other devices, he can restore the remaining days using the same iTunes account.
Unfortunatly Apple reject the app using this reasons:
"
11.7: Apps that use IAP to purchase items must assign the correct Purchasability type
11.7
We found that the Purchasability Type for one or more of your In App Purchase products was inappropriately set, which is not in compliance with the App Store Review Guidelines.
'3 mese' is set to Non-Consumable. However, based on product functionality, it would be more appropriate to use the Non-Renewable Subscription In App Purchase type because the service offered by your application requires the user to make an advance payment to access the content or receive the service.
"
They suggest me to use Non-Renewable Subscription, but I dont have free price in Non-Renewable Subscription, so its useless for me.
In wich way I can achive my goal ?
Should I use KeyChain to store some identifier ?
But in this way the user will have 3 month in each device and I will not able to identifier uniquely on my server and, in addition, formatting the iphone he will have another 3 months of free use
Maybe in the app could I force the user to create an account on my server (or unsing parse.com for example) to have 3 month free ? Anyway the user could create several fake accounts except if I ask for personal data as phone number...but I think that Apple could reject the App if I ask personal data
What is the best choice be adopted in these cases?
For this I would firstly, create a back-end system. Possibly using Parse.com. Then I would register the users UDID when they sign up to the app. This way its the device that they have registered not just the app. Then create a code that will allow them to access the app but perform a check in the database on parse to see whether or not they are allowed the free content. If not, then show the payment options.

We are developing one iOS application for iPhone which will free features as well app will have premium features with 4 in app purchase auto-renewable subscription options as below:
Single monthly subscription
Single yearly subscription
Family monthly subscription
Family yearly subscription
We will have one store screen inside the application which will have options to subscribe to various subscriptions which our app provides.
We found that user can go to device settings and manage their In-app purchase subscriptions.
We are also planning to provide options like user can upgrade from one subscription to other and user should also be able to down grade their subscription which would be all of the same options in reverse and back to the free version
Possible upgrading option:
Free to Any 4 subscription options
Single monthly to single yearly
Single monthly to family monthly
Single monthly to family yearly
Family monthly to family yearly
Possible down grading options:
Family yearly to family monthly
Family yearly to single monthly
Family monthly to single monthly
Single yearly to single monthly
From any 4 subscription options to Free version
Note:
According to Apple we can not use Apple family sharing option to share In App purchases so we are developing our own family sharing option in application. (Reference: https://support.apple.com/en-in/HT203046)
Queries:
We have some doubts how we can manage the subscription in our iOS application?
How device settings options will show our 4 In App Purchase options for upgrading and degrading form one option to other?
What are the consideration we need to task care as an iOS developer for restoring the auto renewable subscription? we are not clear with the possible scenario if user try to restore using iTunes account with multiple user accounts in our app, what are the preventions we can take care which apple allows while user buy subscription one time and try to restore on multiple user account?
Apple will reject custom family sharing option using auto renewable subscription option?
What are the points we need to take care at our end which apple will not handle if we can go with above features?
What are the possibilities of violating the apple guidelines and app rejection if we are going with above features with iOS application?
It will be great help to us if any one can share their views or provide some guidance on which way we should go or if we are going off track from the apple policy.... all those kind of your feedback will help us to get things moving over here.
Thanks
We have some doubts how we can manage the subscription in our iOS application?
Because you are using your own user management system, you should persist the state of a subscription associated to the user in your database. When the user creates a purchase in the app, the app should send this receipt on to your API which will then proceed to validate it.
Once persisted, enqueue a scheduled process to run on the Subscription Expiration Date to update the record and ad infinitum until the expiration date is no longer in the future.
Your app should query your API when the user opens the app to determine their subscription status. Don't rely on the receipt locally in the app as your user's family member devices will not have this purchase associated.
How device settings options will show our 4 In App Purchase options for upgrading and degrading form one option to other?
If all products listed in iTunes Connect are of the same "Subscription Family", they will appear in the Subscription Management page in the users iTunes account.
When a user switches between products a transaction will be created and a SKPaymentTransactionStatePurchased event will be added to the SKPaymentQueue. This will be a new transaction with the same Original Transaction Identifier as the first purchase made with a product from the same Subscription Family with the Product Identifier reflecting the new product.
For this reason, you want to have your transaction observer in your app running in the background to receive any new transactions. When a new transaction is received you can either a) send the whole receipt to your API or b) inform your API that a new transaction has been received and re-validate the receipt that was persisted.
Going with (a) may become problematic as the receipts will become larger over time requiring more bandwidth from the user each time.
Going with (b) also has it's drawbacks because you can get into trouble with edge cases like the user switching iTunes accounts. A solution for this is to store the apps identifierForVendor with the receipt, and require the app to send the whole receipt if it does not match. Most of the time you will just be informing the API that a transaction has occurred, and on the few occasions that the identifier doesn't match it will send along a new receipt.
What are the consideration we need to task care as an iOS developer for restoring the auto renewable subscription? we are not clear with the possible scenario if user try to restore using iTunes account with multiple user accounts in our app, what are the preventions we can take care which apple allows while user buy subscription one time and try to restore on multiple user account?
When restoring, a new transaction with a new transaction ID will be created, the original transaction ID will be the same though. If you create a transactions table in your database, you can ensure a transaction and it's original transaction is only ever associated to a single user, thus preventing users restoring purchases on other devices with a different user and gaining access to the subscription.
A restored transaction will be pushed onto the queue with SKPaymentTransactionStateRestored and so when this happens simply I advise sending the receipt to your API and process the receipt normally; associating any new transactions to the original user.
Apple will reject custom family sharing option using auto renewable subscription option?
I doubt it, but I am not Apple so don't take my word for gospel. Spotify have a similar scheme called "Spotify Family" where a user can share their Spotify account with their family, not sure if this is enabled for their iTunes app though.
What are the points we need to take care at our end which apple will not handle if we can go with above features?
You need your own API with user management and family association
Your users need to sign-in/register on your app
You will need to prevent family users from purchasing if their parent account already has a purchase.
Persist receipts and the identifierForVendor in the database.
Handle receipt validations using the validation API.
Persist a table of transactions and consider this table self-referential so that a transaction can belong to an original transaction through the original_transaction_id. Ensure the transaction_id column is unique.
Validate the receipt each time a transaction is due for renewal.
What are the possibilities of violating the apple guidelines and app rejection if we are going with above features with iOS application?
I see nothing in the guidelines except for section 17.2:
Apps that require users to share personal information, such as email address and date of birth, in order to function will be rejected
I think this one is a little contradictory, since in 17.5 it states:
Apps that include account registration or access a user’s existing account must include a privacy policy or they will be rejected
I guess by this, it means a user must be able to use the app without requiring registration, but I know of many examples of apps that do exactly this.
I intend my app to gain access to my server after the in-app purchase is complete. This access requires real work, and data & traffic ($$).
A typical client might own anywhere up to a couple of hundred devices (and I assume on one account, for their simplicity).
Thus I only get the one payment across many, many devices interacting with the server.
I'm not trying to be stingy - but can I prevent multiple devices sharing the same purchase (in my case server access)?
Or do I implement another method for selling access?
You'll have to implement another method. Apple's guide explicitly states that:
Users can restore products that they previously purchased—for example, to bring content they’ve already paid for onto their new phone.
If the same iTunes account is associated with more than one device then Apple requires any purchases to be available on all those devices.
#Tommy is correct - regarding non-consumable IAPs. However, you could implement a non-recurring subscription in-app purchase instead and give each device a unique identifier. When the user attempts to access the server, you could see if that identifier is in your database (if the user has purchased the IAP), and determine whether or not they need to purchase a subscription. Even though you may not want a subscription-based service, you could probably make a membership for a very long period of time like 10 years (it's not required to be selected in iTunes Connect) and handle it that way. Only issue is that you need to figure out a way to give each device a unique ID that won't change.
Further to the #Tommy answer, in the February 3, 2014 version of Apple's Getting Started with In-App Purchase on iOS and OS X it says:
There are a handful of important guidelines to keep in mind as you design your application:
- You must make your In-App Purchase items available to all of the devices registered to a user
and
Users view the items they purchase as theirs to keep and permanent. Therefore be sure
purchased items are available in all instances of your app running on all the devices the user
owns, even after your app is deleted from a device, reinstalled, or downloaded to a new device.
and
For Non-Renewing Subscriptions, [blah, blah, blah]..
Additionally, your application must include a mechanism to deliver the purchased Non-
Renewing Subscription In App Purchase to all iOS devices owned by a single user.
Looks like there is no way to restrict items to a single device :(
I am planing to publish an iOS app. App should be Free for first 1 month from installation in the Device. Once the 1 month period is over , user has to subscribe to use the application every month by paying some X amount.
1) Will apple allows such applications ?
2) If allows, how to achieve this kind of Payments ?
3) How to prevent user to access the app after 1 month. (Calculation of the Days)?
4) Should i reinstall the app after subscription ?
IAP is supposed to be used to provide additional content and features to an already functional app.
If you render your app useless or without functionality after a month, it will probably be rejected, or banned after approved. I believe you can't have an app that will simply say "Your trial expired.".
In my opinion, you would need to think of a functionality that you can provide to all users, regardless of they paying for it or not, and have the premium or the extra functionality purchased as a In-App Purchase.
Apple does not allow free trials in the app store. If you try to do this, your app will get rejected. Still, there is one category of app where Apple does allow a free trial: apps with auto-renewing subscriptions. These were originally intended for (and only allowed with) Newsstand apps where the subscription is for getting new content such as magazine editions etc.
Apple recently allowed the use of auto-renewing subscriptions in non-Newsstand apps but it's still a very grey area as to what exactly Apple will allow with these. Usually the subscription will have to provide some kind of periodic new content in your app. I agree with those who recommend against using them.
I am stuck with one of the in-app purchase rejection issue in my app and need some help on this.
What this in-app for?
In our app we have options for user to become premium user. A user can become premium user to enjoy some benefits and it is tied to time. There are two in-app products which defines them
One month premium service.
One year premium service.
Since these are time based service, user expects these service should be made available for that user once he/she purchase the product for the specified time, from all his/her other devices. In order to track whether the user is premium service user or not, once the purchase is done, the app writes a entry in server about premium service. So when user uses other device and logs in, he/she can enjoy the premium service without any issues. For this reason I created the above mentioned products as "consumable", thinking that it is controlled by our server there will be no issues. But apple came back with rejection and asked me to change the products to "non-renewing subscription".
Here is what apple says about this
We found that the Purchasability Type for one or more of your In App Purchase products was inappropriately set, which is not in compliance with the App Store Review Guidelines.
"Premium account service for 1 month and 1 year" IAPs are set to Consumable.
However, based on product functionality, it would be more appropriate to use the Non-Renewable Subscription In App Purchase type because the service offered by your application requires the user to make an advance payment to access the content or receive the service.
The Purchasability type cannot be changed once an In App Purchase product has been created. Therefore, you will need to create a new In App Purchase product with the correct Purchasability Type. To create a new In App Purchase in iTunes Connect, go to Manage Your In App Purchases, select your app, and click "Create New". The current product will show in iTunes Connect as "Rejected".
Non-Renewable Subscription content must be made available to all iOS devices owned by a single user, as indicated in Guideline 11.6 of the App Store Review Guidelines:
11.6 Content subscriptions using IAP must last a minimum of 7 days and be available to the user from all of their iOS devices
If you choose to use user registration to meet this requirement, please keep in mind that it is not appropriate to require user registration. Such user registration must be made optional. It would be appropriate to make it clear to the user that only by registering will they be able to access the content from all of their iOS devices; and to provide them a way to register later, if they wish to access the content on their other iOS devices at a future time.
For more information about Purchasability Type, please to refer to the iTunes Connect Developer Guide.
Now I have created new in-app products which are non-renewing. But this works the same way as I mentioned earlier, i.e. the server keeps track of whether user is premium user or not, expiry date. When user goes to other device and does login, the app comes to know whether user is premium or not and based on that app works.
But I have couple of questions on this,
Should I need to provide the "Restore" button in the app? If so what is the purpose and how it works?
Since the user can access this service only after doing login to the app (it is different from app store account). Will these two logins make any issue?
Please share your valuable inputs.
It is highly unlikely that the user will end up in a situation where they won't be able to use your app unless they restore their purchases, however it is still possible. Imagine your server goes down for a day and during that day some user purchases a subscription, gets a new iPhone, installs your app on the new device and then wipes their old iPhone. I can think of a couple of other, equally unlikely, but still possible situations (Apple receipt validation server going down, etc) in which the purchase receipt will get lost in transit. It's best to provide the button, and if Apple thinks that you need it in your app, you will have a hard time convincing them otherwise.
If by "two logins" you mean user having to log in to your system and then log in to the App Store to purchase the subscription, that should not be a problem.
I recommend you make the changes Apple requested to the Purchasability Type and then re-submit. If you need to clarify a lack of a restore button put it in the notes for the reviewer
I am implementing an App with in app purchase of type:non-renewing subscriptions.
according to apple documents:
If your app uses non-renewing subscriptions, your app is responsible for the restoration process.
FROM HERE
My question is, if the restoring is mandatory by apple, how to prevent thousands of users sharing one apple account with only one description?
For example, if in my app, you pay $0.99 that can use this app for 10 days, from apple's requirements, the user must be able to use app within 10 days on any his/her devices, with simply enter the credentials. However, if the user set a simple account credentials and share it with 100 people, then, the 100 people don't have to buy the subscription anymore and can use the app free during the 10 days.
Some people keep assert that people won't share their account... how do you know that? i saw people register some apple id exclusive for sharing apps and games, and only need to pay once.
Besides, i don't implement my own server and my App don't need one. Is there a way to prevent this?
Thanks in advance
Since non-renewing subscriptions seem to require the app (developer) to use a separate (non-Apple) server to deal with the restore process (for example, see How to support multiple devices with non-renewing In-App Purchase?), why not have that server keep track of the number of restores per "user"? Then you could impose a maximum number of restores per "user". Each installed app that has made a purchase could have its own unique_token (for example, see app rejected.how to track user non-renewing subscription). The user would then have to have a username/password, which would be associated with the unique_token, in order to do a restore (for example, see Restore transactions for Non-renewing subscriptions without registration; and see Registration should be always optional on non-renewing subscription?).
