Honestly, this is a much more complex question, and there is no real true blue number, as the views and statuses shifted throughout the reign of the Nazis, and as the war progressed and got worse. Anywhere from a couple thousand to possibly tens of thousands of German Jews (or part Jews) were spared at one point or another. For example originally German Jewish veterans of World War I were for many years given a pass, not rounded up, and not sent to camps. As the war progressed, their special status lessened, to only German Jews who won the Iron Cross or any other military award for bravery in combat.

Other Jews that were given passes, and not rounded up and sent to camps were German Jews who worked in highly technical fields that were irreplaceable to the war effort. There were ghettos in some of the larger German cities, like Berlin, where German Jews lived right up until the end of the war, without ever being sent to a camp, because they worked in the armaments industry. These Jews were places in ghettos, and were given flak obviously, and did not have it easy, but because of their skilled labor they were not sent to concentration camps, or death camps. Although, this did not spare these Jews from the occasional harassment by the Gestapo, nor did it spare them from Allied bombing raids on factories.

Things also became complex when dealing with the Wehrmacht (the military), specifically the Heer (the Army). The German Army of World War II had its roots deeply embedded in Prussian militaristic ideals and principals. The German Army was supposed to not be political, and just fought for their country and people, and not for any political purpose (this had caused some issues with the Nazis prior to and during the war). The Army was supposed to stay out of all political affairs, and act as a well disciplined machine that was loyal the country and people FIRST. So when Hitler comes about, with his Nazis, and they take control, they made a few attempts to Nazify the Army (which never was fully successful, and only partially successful after the July 20, 1944 Attempted Assassination of Hitler). However, Nazifying the Army was a big challenge for Hitler that never was fully successful. So where am I getting at with this? At least partial Jewish German soldiers were hidden among the ranks of the Wehrmacht. They were sheltered there by the people around them, and at times even legally Aryanized. The Army at its core did not care about your religious or political leanings, yes as the war progressed and more radical Nazi Generals became prevalent and put in higher places, did this start to become a problem, but as a whole, one could be spared the persecution, if they were in the army. But this also meant fighting for a country, and possibly dying for a country, who's political rulers despised your existence. Of course if the SS / Gestapo found out, it could become an issue, but depending on who you knew, your Aryanized status etc... you could be spared. There are some books like "Hitler's Jewish Soldiers" (and the follow up "The Lives of Hitler's Jewish Soldiers") that go in to all of this. The numbers are not exact, but in the case of escaping persecution for being Jewish /part Jewish by being in the military, helped several thousand to tens of thousands of German Jewish men. A possible notable example of this, which was occasionally brought up and investigated was Field Marshal Erich von Manstein, who was adopted as an infant, but originally of Polish / Prussian nobility as well (von Lewinski). His biological family having some Polish blood and possible Jewish blood did cause some investigations and some accounting for his heritage. Obviously this never became a true blue issue, and some of his units under his command on the Eastern Front even participated in the Holocaust. But one could slip by in the German military, if lucky, and smart.

Now we get to another weird case. Heinrich Himmler even had about two thousand Jews who at the end of the war he negotiated their release and transportation to neutral countries, because he feared reprisals from the Allies, and wanted to show that he was somewhat of a decent guy. He negotiated this release of Jews with the World Jewish Congress... most were aristocratic European Jews who were wealthy and powerful prior to the Nazis.

The thing is not many were outright given protection by the Gestapo / SS, in your case, and in the last case I gave that puts the numbers in the few thousands range. HOWEVER, there were far more who slipped through the cracks, or managed to get by under Nazi rule... especially in the Wehrmacht.
